A buoy is floating at sea. If the buoy oscillates with a frequency of 0.50 Hz, and an amplitude of 0.50 m, how long does it take for the buoy to move a vertical distance of 2.0 m? Give your answer in seconds.

A2 kg ball travellng to the right with a speed of 4 m/s collidees with a 5 kg ball traveling to the left with a speed of 3 m/s. take right to be the positive direction. what is the total momentum of the two balls before they collide? what is the total momentum of the two balls after they collide?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

Explain why you think this diagram shows what happened to the carbon in the biodome.
