As viewed from Earth, the light from a star has

lower frequencies than the light emitted by the

star because the star is

(1) moving toward Earth

(2) moving away from Earth

(3) stationary

What are three processes in the body that are fueled by chemical potential energy?

A sample of ice at 0°C has a mass of 23 g and a volume of 25 cm^3. Why does ice float on water? The density of water is 1 g.

Potential energy and kinetic energy are created when work is done to change a position (PE) or a state of motion (KE). Ignoring friction, how does the amount of work done to make the change compare to the amount of PE or KE created? a.

The wavelength of a wave is the wavelength of a wave is how strong the wave is. equal to the speed of the wave times the wave's frequency. the distance between where the wave is emitted and where it is absorbed.

What is a carbon whip?
