In a system with no friction what is the mathematical relationship between kinetic and potential energy? 1. As potential Energy increases, kinetic energy increases
2. Potential and kinetic energy are always the same
3. As kinetic energy increases, potential energy decreases

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.
