Consider the following special cases of collisions. in all cases, a cart of m 1 comes in with a velocity v and hits a cart m 2 at rest. most of these are answerable with either intuition or with mathematics. compute v 1 v and v 2 v 2 when: the collision is elastic, and both carts are the same mass? the collision is inelastic, and both carts are the same mass?

Starting with only the balmer series light (visible light), how could we ensure that the solar panels generate a current that mark can use for his power station? a)by gradually increasing the brightness (amount) of light that we shine on it. b)by gradually increasing the frequency of the light we shine on it. c)by gradually increasing the wavelength of the light that we shine on it.
