  1. Ultraviolet light has a shorter wavelength than visible light. Which of the following is another way ultraviolet light can be compared to visible light? (S8P4a) A. Ultraviolet light has a lower frequency than visible light. B. Ultraviolet light has a higher frequency than visible light. C. Ultraviolet light travels faster than visible light. D. Ultraviolet light travels slower than visible light. When air near the ground is warmed by sunlight, which of the following occurs? (S8P2) A. The warm air radiates and becomes cool again. B. The warm air evaporates into the cooler air. C. The warm air expands and rises, resulting in convection. D. The warm air loses its ability to hold water and precipitates.

  2. Some campers are sitting around a campfire outside their tent. Which product of the fire is in the form of electromagnetic waves? (S8P4a)A. light B. smoke C. smell • water vapor A flowing stream contains water at 18°C. Cans of soft drinks at 28°C are lowered into the stream. Which of the following will most likely occur? (S8P2) A. The soft drink cans will absorb cold energy from the stream’s water. B. The cans will cool until their temperature is the same as the stream’s temperature. C. The temperature of the soft drinks will not change since the cans are sealed. D. The temperature of the cans will decrease to freezing as long as the stream is flowing

  3. A person produces two sound waves with a flute, one immediately after the other. Both sound waves have the same pitch, but the second one is louder. Which of the following properties is greater for the second sound wave? (S8P4a) • Frequency • Amplitude • Wavelength • Speed in air Many electronic devices use batteries as a source of energy. The batteries will eventually wear out. In terms of the Law of conservation of energy, what has occurred? (S8P2) A. The Law Of Conservation of Energy is not correct. B. All of the energy has been transformed into other forms of energy. C. All of the energy has been converted into mass. D. The Law of conservation of energy does not apply in this situation.

  4. Vibrations inside the ear are amplified by the three bones namely the _________ in the middle ear. (S8P4d) • hammer, anvil and stirrup • hammer, anvil and pinna • hammer, cochlea and stirrup • auditory bone, anvil and stirrup Since energy cannot be created or destroyed. The amount of energy in the universe is constant. Why then is there so much concern over a world wide energy shortage? (S8P2) • Even though energy cannot be destroyed, most of it is located in the ocean. • We have used up the most convenient forms of energy. • Energy is only available when the sun is shining. • We cannot find the energy.

  5. By what process does a lens focus light? (S8P4b)A. reflection B. refraction C. congregationD. dispersion A student in a laboratory transfers a beaker containing a hot solution from the lab table to a cool water bath. Which of the following parts of the system experiences an increase in heat energy? (S8P2) A. beaker B. lab table C. solution D. water bath
