A spring deforms 5 cm when we attach a 2 kg object:
a) What is the spring constant?
b) How far will it stretch with 800 g on it?

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

Several mountains together form a mountain . a few of these combined form a mountain system. several systems combined form a mountain , which can stretch thousands of miles in length.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain
