In the 25-ft Space Simulator facility at NASA's Jet Propulsion Laboratory, a bank of overhead arc lamps can produce light of intensity 2500W/m2 at the floor of the facility. (This simulates the intensity of sunlight near the planet Venus.)
A) Find the average radiation pressure (in pascals) on a totally absorbing section of the floor.
B) Find the average radiation pressure (in atmospheres) on a totally absorbing section of the floor.
C) Find the average radiation pressure (in pascals) on a totally reflecting section of the floor.
D) Find the average radiation pressure (in atmospheres) on a totally reflecting section of the floor.

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.)
