Suppose that some time in the future we decide to tap the moon's rotational energy for use on earth. in additional to the astronomical data in appendix f in the textbook, you may need to know that the moon spins on its axis once every 27.3 days. assume that the moon is uniform throughout. how much total energy could we get from the moon's rotation? the world presently uses about 4.0 x 10^20 j of energy per year. if in the future the world uses five times as much energy yearly, for how many years would the moon's rotation provide us energy? is that cost effective?

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
