WAVES AND SOUND A girl, standing 150m in front of a tall building, fires a shot using a starting pistol. A boy, standing
350 m from the girl, hears two bangs 1s apart.

From this information, what is the speed of sound in air?
C 500 m/s
D 650m/s
B 350m/s
A 300 m/s

The density of a liquid could be found by using

Starting with only the balmer series light (visible light), how could we ensure that the solar panels generate a current that mark can use for his power station? a)by gradually increasing the brightness (amount) of light that we shine on it. b)by gradually increasing the frequency of the light we shine on it. c)by gradually increasing the wavelength of the light that we shine on it.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
