Look at the simple machine shown below to determine the mechanical advantage

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.)

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?
