2) An object tied to the end of a string moves in a circle. The force exerted by the string depends on the mass of the object, its speed, and the radius of the circle. What
combination of these variables expresses the relation?​

The force will determine the acceleration.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
