When a puddle dries up what are the particles really doing

A bottle dropped from a balloon reaches the ground in 20 s. determine the height of the balloon if (a) it was at rest in the air and (b) it was ascending with a speed of 50 m/s when the bottle was dropped.

Which statement about the effects of medium on the speed of a mechanical wave is true?

What is the speed of a wave that has a wavelength of 2 and a frequency of 2.5

On a hot day, a concrete sidewalk feels hotter than the water in a small swimming pool. And a sandy beach feels hotter than the lake or ocean. What do these observations tell you about temperature changes when different materials are heated?

Along some shorelines, incoming waves cause the water to simply rise and fall rather that form a surf zone. What does this tell you about these shorlines?

Which word best describes the rate at which work is done? work energy power velocity

Explain why a valve would last longer in the pulmonary position than in the aortic position

Think about the process of heating water, the heating and upward motion of hot steam and air, and the spiral spinning. For these events, list each form of energy associated with the heat source, the water, the steam and air, and the spiral.

A long rope with mass m is suspended from the ceiling and hangs vertically. A wave pulse is produced at the lower end of the rope, and the pulse travels up the rope.
