A 33 kg gun is standing on a frictionless sur- face. The gun fires a 55.7 g bullet with a muzzle velocity of 318 m/s. The positive direction is that of the bullet. Calculate the momentum of the bullet immediately after the gun was fired.

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.
