An asteroid is coming towards the Earth. If the centers of the Earth and the asteroid are 1.0 x 10^9m apart and the force of gravity between them is 50.0N then what will the force of gravity between them be if the asteroid gets to a distance of 1.0 x 10^7m?

Heena wants to measure the volume of a ball that is 24 cm across. how should she set up her equation?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

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
