She is now best known for her metaphysical novels, principle She Came to Stay and The Explain, and for her treatise "The Second Sex," a detailed analysis of women's oppression and a foundational tract of contemporary feminism. If behind encounter a sonic boom, is that evidence that an aircraft of some sort exceeded the speed of sound moments ago to become supersonic? And newly discovered radioactive the previous 14 years was the nebulae redshift dating could be interpreted, like Einstein's equations, as implying an expanding universe.

As more devices are connected to the lines, more pathways are provided for current, lowering the combined resistance of this circuit. Therefore, a greater amount of current occurs in these lines. The resulting heat of overloaded lines may be sufficient to melt the insulation and start a fire. What is meant by a short circuit? A short circuit is a circuit that has a path of much less resistance and therefore the current only takes that path.
Term applied to portions of an electric circuit that are connected at two points and provide alternative paths for the current between these two points. Term applied to portions of an electric circuit that are connected in a row so that the current that goes through one must go through all of them.
Gravitational forces depend on the property called mass. What comparable property underlies electrical forces? The comparable property that underlies electrical forces is charge.
Which has more mass- a proton or an electron? A proton has more mass. In a normal atom, how many electrons are there compared with protons? There are an equal number of protons and electrons in a normal atom. How does a negative ion differ from a positive ion? A negative ion has more electrons than protons whereas a positive ion has more protons than electrons.
Why does the weaker force of gravity dominate over electrical forces for astronomical objects? Because astronomical objects have very large masses, gravity has a greater effect on them. What is the difference between a good conductor and a good insulator? A good conductor allows the movement of electrons and a good insulator stops the movement of electrons.
What are the three main methods of charging objects? Which method involves no touching? The three main methods of charging are charging by contact, charging by friction, and charging by induction. Charging by induction requires no touching. What does it mean to say an object is electrically polarized? When one side of the atom or molecule is induced to be slightly more positive or negative than the other side, it is said to be electrically polarized.
By how much is the electrical force between a pair of ions reduced when their separation distance is doubled? When their separation distance is doubled, the electrical force is reduced by a factor of 4. When tripled, it is reduced by a factor of 9. If you scuff electrons from your hair onto a comb, are you positively or negatively charged? How about the comb? You are positively charged, the comb is negatively charged.
An electroscope is a simple device. It consists of a metal ball that is attached by a conductor to two fine gold leaves that are protected from air disturbances in a jar, as shown in the sketch. When the ball is touched by a charged object, the leaves that normally hang straight spring apart.
The leaves spring apart because they have charges of the same sign and repel each other. Why is a good conductor of electricity also a good conductor of heat? Both heat and electricity are conducted through the movement of electrons. Explain how an object that is electrically neutral can be attracted to an object that is charged. When a charged object is brought close to an electrically neutral object, the particles carrying the same charge repel each other, creating an induced charge in the neutral object.
Imagine a proton at rest a certain distance from a negatively charged plate. Then imagine the similar case of an electron at rest, the same distance away, from a plate of equal and opposite charge. In which case would the moving particle have the greater speed when the collision occurs? The electron would have the greater speed because it has the smaller mass. What is meant by the expression action at a distance?
Action at a distance means an interaction between objects that are far apart. How are a gravitational field and an electric field similar? Both electrical and gravitational fields are a means of exerting forces.
Why is an electric field considered a vector quantity? An electrical field is considered a vector quantity because it has both direction and magnitude. Why are occupants safe inside a car struck by lightning?
Electrons from the lighting bolt mutually repel and spread over the outer metal surface of the car. Although the electric field they set up may be great outside the car, the overall electric field inside the car practically cancels to zero. Can gravity be shielded? Can electric fields be shielded? There is no way to shield gravity because gravity only attracts.
Yes, electrical fields can be shielded. What is the relationship between the amount of work you do on an object and its potential energy? Doing work increases the object's potential energy. How can the electrical potential energy of a charged particle in an electric field be increased? The electrical potential energy of a charged particle can be increased by pushing the charge against the electric field. What will happen to the electrical potential energy of a charged particle in a electric field when the particle is released and free to move?
The electric potential energy will transform into kinetic energy. If you do more work to move more charge a certain distance against an electric field, and increase the electrical potential energy as a result, why do you not also increase the electric potential? The electric potential does not increase because if you increase both the electric potential energy and the charge, then the increase in each cancels out resulting in the same electric potential.
How can electric potential be high when electrical potential energy is relatively low? Electric potential can be high when electrical potential energy is relatively low if the charge is low as well. How does the amount of charge on the inside surface of the sphere of a charges Van de Graaff generator compare with the amount on the outside?
The inside surface is uncharged because all of the electrons move to the outside surface. Imagine a "free" electron and "free" proton held midway between the plates of a charged parallel plate capacitor.
When released, how do their accelerations and directions of travel compare? If we ignore their attraction to each other, which reaches a capacitor plate first? The electron will travel faster and in the opposite direction of the proton, reaching the plate first.
Is it correct to say that an object with twice the electric potential of another has twice the electrical potential energy? It is correct to say that an object with twice the electric potential of another has twice the electrical potential energy only if the charges are the same. Why does your hair stand out when you are charged by a device such as a Van de Graaf generator?
Your hair stands out because each strand of hair becomes charged with the same sign, causing them to repel each other. If you do 12 J of work to push 0. When the charge is released, what will be its kinetic energy as it flies back past its starting point A?
What principle guides your answer? The principle of conservation of energy says that the energy released will be equal to the energy put into the system, so the kinetic energy of the charge as it flies back past its starting point will be 12 J.
Distinguish between a converging lens and a diverging lens. A converging lens is thicker in the middle and rays of light that are initially parallel are made to converge.
A diverging lens is thinner in the middle and the rays of light are made to diverge. Distinguish between a virtual image and a real image. A virtual image cannot be seen on a screen at the image distance because no light is actually directed to the image position. The rays that reach your eye behave as if they came from the image position, however. A real image is formed when light from the object does converge and can be focused on a screen.
There are three convenient rays commonly used in ray diagrams to estimate the position of an image. Describe these three rays in terms of their orientation with respect to the principal axis and focus points. The first ray runs parallel to the principal axis, the second ray runs directly through the center of the lens, and the third ray travels through the focal point and then parallel to the principal axis.
Which instrument- a telescope, a compound microscope, or a camera- is most similar to the eye? The camera is most similar to the eye. Distinguish between farsighted and nearsighted vision. The eyes of a farsighted person form images behind the retina because the eyeball is too short. Farsighted people have to hold things more than 25 cm away. A nearsighted person can see nearby objects clearly, but does not see distant objects clearly because they are focused to near the lens, in front of the retina.
The eyeball is too long. What is astigmatism, and how can it be corrected? Astigmatism of the eye is a defect that results when the cornea is curved more in one direction than the other. Because of this defect the eye does not form sharp images. The remedy is cylindrical corrective lenses that have more curvature in one direction than another.
How could you demonstrate that an image was indeed a real image? To demonstrate than an image was indeed real, you could show that it appears on a screen. Why do you have to put slides into a slide projector upside down? Because the images that are produced will be upside down if you do not, so by putting it upside down the image will appear right side up.
Would telescopes and microscopes magnify if light had the same speed in glass as in air? If light had the same speed in glass as in air, there would be no refraction, and therefore no focusing. Waves spread out when they pass through an opening.
Does spreading become more or less pronounced for narrower openings? What is the spreading called? Does diffraction aid or hinder the viewing of images in a microscope? Diffraction hinders the viewing of images in a microscope. Does wave interference occur for waves in general, or only for light waves?
Give examples to support your answer. Wave interference occurs for waves in general. Wave interference causes beat frequencies in sounds, as well as disturbances in ocean waves. What is the cause of the fringes of light in Young's experiment? The bright fringes of light resulted from light waves from both holes arriving crest to crest constructive interference-more light. What is a diffraction grating? A diffraction grating is a multitude of closely spaced parallel slits.
What is iridescence, and to what phenomenon is it related? Iridescence is the colors produced by the interference of light waves of mixed frequencies in thin films. It is related to the phenomenon of interference. If a soap bubble is thick enough to cancel yellow by interference, what color will it appear if illuminated by white light?
The soap bubble will appear blue when illuminated by white light. How does light from a laser differ from light from an ordinary lamp? Light emitted by a common lamp is incoherent, meaning it has many phases of vibration as well as many frequencies. A beam of light produced by a laser is coherent, meaning it has the same frequency, phase, and direction. Why do radio waves diffract around buildings but light waves do not? Because radio waves have longer wavelengths, they are able to diffract around buildings while light waves are not.
A far-sighted eye whose comfortable reading distance is 80 cm is to be supplied a corrective lens to enable reading at a normal distance of 40 cm. So the object distance is 80 cm and the image distance is 40 cm. What is the focal length of the corrective lens?
What two colors of light will produce magenta? The bending of light as it passes through one medium into another is called. What type of image do mirrors produce? List the following as they appear on the electromagnetic spectrum: Explain why the atomic spectra is considered the "fingerprint" of an element. The atomic spectra is unique for each element. What is a photon? Which theory of light is the photon more consistent with- the wave theory or the particle theory? A photon is a massless bundle of concentrated electromagnetic energy.
The photon is more consistent with the particle theory. How long does light take to travel a distance of one light-year? It takes one year to travel the distance of one light-year. What is the source of electromagnetic waves? Accelerating electric charges are the source of electromagnetic waves. How do the frequencies of infrared, visible, and ultraviolet light compare? Infrared light has a lower frequency than visible light, and visible light has a lower frequency than ultraviolet light.
Different bells and tuning forks have their own natural vibrations, and emit their own tones when struck. How is this analogous to atoms, molecules, and light? Each type of atom, molecule, and light vibrate with its own frequency. Light incident upon a pane of glass slows down in passing through the glass. Does it emerge at a slower speed or at its initial speed?
The light emerges at its initial speed. Will glass be transparent to frequencies of light that match its own natural frequencies? Glass will not be transparent to frequencies of light that match its natural frequency. Why would you expect the speed of light to be slightly less in the atmosphere than in a vacuum? In a vacuum there are no particles for the light to collide with so it travels faster than it would in the atmosphere. When light encounters a material, it can build up vibrations in the electrons of certain atoms than may be intense enough to last over a long period of time.
Will the energy of these vibrations tend to be absorbed and turned into heat, or absorbed and reemitted as light? The energy of these vibrations will tend to be absorbed and turned into heat.
What determines whether or not a material is transparent or opaque? Transparent materials absorb light and then reemit it, opaque materials absorb light without reemission. What evidence can you cite to support the idea that light can travel through a vacuum? The light from the sun is evidence that light can travel through a vacuum. You can get a sunburn on a sunny day and on an overcast say.
But you cannot get a sunburn if you are behind glass. Because ultraviolet light vibrates at the natural frequency of glass, it does not pass through glass.
Pretend a person can walk only at a certain pace, no faster, no slower. If you time her uninterrupted walk across a room of known length, you can calculate her walking speed. If however, she stops momentarily along the way, the extra time spent in her brief interactions gives an average speed across the room that is less than her walking speed. How is this like light passing through glass? How is it not? Light slows down when passing through glass, so its average speed would be less than its speed if it just traveled through the air.
However, the light does not stop as the person did. Short wavelengths of visible light interact more frequently with the atoms in glass than do longer wavelengths. Which do you suppose takes the longer time to get through glass, red light or blue light?
Blue light takes longer to pass through glass than red light. Why does a high-flying plane cast little or no shadow on the ground, while a low flying plane casts a sharp shadow?
The penumbra of the high flying plane fills the umbra. What percentage of light would be transmitted by two ideal polarizing filters, one atop the other, with their axes aligned? With their axes crossed at right angles? List the order of colors in the color spectrum. The order of the colors in the color spectrum is red, orange, yellow, green, blue, and violet.
Are black and white real colors, in the sense that red and green are? Black and white are not real colors in the sense that red and green are. White is a combination of all colors, and black is the absence of light.
Objects appear white when they reflect all visible light frequencies, and black when they absorb all visible light frequencies. A vibrating tuning fork emits a sound. What is emitted by the vibrating electrons of an atom? Light is emitted by the vibrating electrons of atoms.
What happens to light of a certain frequency that encounters atoms of the same resonant frequency? Light of a certain frequency that encounters atoms of the same resonant frequency is absorbed. Why does the color of an object look different under a fluorescent lamp from the way it looks under an incandescent lamp?
An incandescent lamp emits light of all the visible frequencies, but is richer toward the lower frequencies, enhancing the blues. A fluorescent lamp is richer in the higher frequencies, so blues are enhanced when illuminated with fluorescent lamps. What color s of light does a transparent red object transmit?
What color s does it absorb? A transparent red object transmits red light. It absorbs all other frequencies. What is the name of the color produced by a mixture of green and blue light? The name of the color produced by a mixture of blue and green light is cyan. What are complimentary colors? Complimentary colors are colors that produce white when added together. What color is the compliment of blue? Yellow is the compliment of blue. What is meant by the normal to a surface? Incident rays and reflected rays make equal angles with a line perpendicular to the surface, called the normal.
What is the law of reflection? When you view your image in a plane mirror, how far behind the mirror is your image compared with your distance in front of the mirror? When you view your image in a plane mirror, your image is as far behind the mirror as you are in front of the mirror.
Does the law of reflection hold for diffuse reflection? In a diffuse reflection, although the reflection of each single ray obeys the law of reflection, the many different angles that incident light rays encounter cause reflection in many directions. If light had the same speed in air and in water, would light be refracted in passing from air to water?
If light had the same speed in air and in water, it would not be refracted in passing from air into water. If you can see the face of a friend who is underwater, can she also see you? If you can see the face of a friend who is underwater, she can also see you.
Is a mirage a result of refraction or reflection? On hot days there may be a layer of very hot air in contact with the ground. Since molecules in hot air are farther apart, light travels faster through it than through the cooler air above.
The speeding up of the part of the wave nearest the ground produces a gradual bending of light rays. This can produce an image that appears upside down to an observer to an observer, just as if it were reflected from a surface of water.
But the light is not reflected; it is refracted. What conditions are necessary for viewing a rainbow in the sky? The conditions for seeing a rainbow are that the sun be shining in one part of the sky and that water droplets in a cloud or in falling rain be in the opposite part of the sky. How is a raindrop similar to a prism?
A raindrop is similar to a prism in the way that it disperses light in to its spectral colors. What is the critical angle in terms of refraction and total internal reflection? The critical angle is the angle required for light to experience total internal reflection rather than refraction. Why are optical fibers often called light pipes?
Optical fibers are sometimes called light pipes because they pipe light from one place to another. Contrast the types of reflection from a rough road and from the smooth surface of a wet road to explain why it is difficult for a motorist to see the roadway ahead when driving on a rainy night. The reflection from a dry road is diffuse due to irregularities in the road, so light bounces in all different directions.
The reflection from a wet road is mirrored, so the light bounces back into the driver's eyes, making it difficult to see ahead of them. A hypnotist swings his watch from a 0. What is the period of the swing? Which of the following does not travel as a transverse wave? Rubbing a finger around the rim of a crystal glass will produce a specific sound characteristic of the crystal. This is said to be the crystal's.
Sound waves cannot travel through which of the following substances: How are frequency and pitch related? When frequency increases, pitch increases. Which of the following has the least energy? If two notes are played, one at Hz and the other at Hz, what is the combined beat frequency? The combined beat frequency is 3 Hz. Explain what the Doppler Effect is and how it can be heard when a car horn is being sounded.
Who notices the effect? Who does not notice the effect? The Doppler effect is an observed shift in frequency received due to motion of a vibrating source toward or away from a receiver. When a car horn is being sounded, the change in pitch can be heard as the distance from the car to the observer changes. The pitch increases as the car gets closer and decreases as it gets farther away. The observer notices the effect. The person in the car does not notice the effect. The range of electromagnetic waves extending from radio waves to gamma rays.
A wave that is partly electric and partly magnetic and carries energy. Emitted by vibrating electric charges. Suppose that a pendulum has a period of 1. But, the term still held a lot of weight. Here's an excerpt from our Word of the Year announcement in The national debate can arguably be summarized by the question: In the past two years, has there been enough change?
Has there been too much? Meanwhile, many Americans continue to face change in their homes, bank accounts and jobs. Only time will tell if the latest wave of change Americans voted for in the midterm elections will result in a negative or positive outcome. This rare word was chosen to represent because it described so much of the world around us.
Tergiversate means "to change repeatedly one's attitude or opinions with respect to a cause, subject, etc. And so, we named tergiversate the Word of the Year. In a year known for the Occupy movement and what became known as the Arab Spring, our lexicographers chose bluster as their Word of the Year for Here's an excerpt from our release that year that gives a pretty good explanation for our choice:. We got serious in Here's an excerpt from our announcement in Things don't get less serious in Our Word of the Year was exposure , which highlighted the year's Ebola virus outbreak, shocking acts of violence both abroad and in the US, and widespread theft of personal information.
Here's what we had to say about exposure in From the pervading sense of vulnerability surrounding Ebola to the visibility into acts of crime or misconduct that ignited critical conversations about race, gender, and violence, various senses of exposure were out in the open this year. Fluidity of identity was a huge theme in Racial identity also held a lot of debate in , after Rachel Dolezal, a white woman presenting herself as a black woman, said she identified as biracial or transracial.
Our Word of the Year in reflected the many facets of identity that surfaced that year. In , we selected xenophobia as our Word of the Year.
