Calculate the impulse experienced by a 65.8-kg halfback encountering a force of 1025 N for 0.350 seconds

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

If the pressure in a gas is doubled while its volume is held constant. true or false

If frequency goes up, what happens to wavelength? does it get shorter or longer?
