A steam shovel raises 450.0 kg of dirt a vertical distance of 8.6 m. The engine provides 2.00 x 105 J of energy as heat for the steam shovel to lift the dirt. How much work, in Joules, is done by the steam shovel?

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.

As the distance from a magnet increases, what happens to the magnet force?

Ashot putter releases the shot some distance above the level ground with a velocity of 12.0 m/s, 51.0 ∘above the horizontal. the shot hits the ground 2.08 s later. you can ignore air resistance. how far did she throw the shot?
