Tim pushes a box with a constant force 250 N at an angle of 45° to the horizontal. If he pushes the box 22 meters, how much work has he done? Keep 4 significant figures.

The sun generates both mechanical and electromagnetic waves. which statement about those wave is true?

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.
