A 4-kg object is moving with a speed of 5 m/s at a height of 2 m. The kinetic energy of the object is approximately _J.

What color would an object that reflects green and blue light appear to be in white light? a. blue b. cyan c. magenta d. black

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.)

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =
