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:

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)
