The grid floor in an operant chamber is electrified. each time a rat presses a lever, however, the shock is turned off for one minute. the rat quickly learns to press the lever the second that the grid becomes electrified. lever pressing has been:

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

This energy transformation diagram represents the energy of a skateboarder moving along a half-pipe. as she skates toward the top of the half-pipe, her original kinetic energy is converted to potential energy and friction. how much of the energy is potential?

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
