In part h, you discovered that the luminosity of a light bulb increases if the current increases. the rate at which electric potential energy is converted into heat depends on the current flowing through the bulb and the voltage across the bulb. this energy is supplied by the battery. mathematically, the luminosity p of the light bulb is given by p=δvi, where δv is the voltage across the bulb and i is the current. what happens to the luminosity of the light bulb if the voltage of the battery is doubled? (note that the phet simulation does not display a numerical value for the luminosity, so you should use the relationship between the luminosity, the voltage across the bulb, and the current.)

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. what is the best explanation of the relationship between wavelength and wave energy? a) wave energy is related only to frequency, not wavelength. b) longer wavelengths have lower frequencies but higher energy. c) the shorter the wavelength, the lower the frequency and the higher the energy. d) the shorter the wavelength, the higher the frequency and the higher the energy.

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
