A 25.0 Kg box is being pushed by a man horizontally. If the man applies a force of 200.0 N to keep the box moving at a constant velocity, what is the force of friction on the box? (b)
What is the μ\muμ k on the box? (Show your work)

(c)
What was the net force on the box

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?
