An electric car is being designed to have an average power output of 4,600 w for 2 h before needing to be recharged. (assume there is no wasted energy.)

how much energy would be stored in the charged batteries? =j
the batteries operate on 80 v. what would the current be when they are operating at 4,600 w? =a
to be able to recharge the batteries in 1 h, how much power would have to be supplied to them? =w

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.

Protons have a positive charge and, collectively, give an element its atomic number.
