- A wooden crate that measures 2.0 m long and 0.40 m wide rests on the floor. If the crate has a weight of 600.0 N, what pressure does it
exert on the floor?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
