As a cat pounces on a mouse, her muscles burn 10 units of potential energy (which the cat previously gained from eating). however, the pounce itself only required 4 units of kinetic energy. how many units of energy were dissipated as heat?

What is a frequency of a wavelength

Will you chech and finish these for me, because i am stumped with them.

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
