1. A 2-kg object is moving in a uniform circular path with a radius of 5 m and a tangential velocity of 25 m/s.
a. What is the centripetal acceleration of the object?
b. What is the magnitude of the centripetal force acting on the object?
C. How long does it take for this object to travel around the circle once (in seconds)?

If forces acting on an object are unbalanced, which factors may result fron an unbalanced force? check all that apply

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

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.
