Acrate is to be pulled across the floor. the crate will experience a force of friction of 34 n. you pull on the crate with a force of 75 n. the mass of the crate is 8.5 kg.

what is the net force acting on the crate?

what is the crate's rate of acceleration?

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.
