In a balanced system, the total energy should always stay the same. The total energy is the sum of the potential and the kinetic energies. If the potential energy increases, then the kinetic energy should decrease. This happens to keep the system under a state of balance.

The answer would be D) Kinetic friction because kinetic means during and in motion and happening/occurring so since the box is moving now across the floor, its in motion so that's why its D).
Answer:
White light viewed through a prism is an example of a visible spectrum.
The answer is 1.01 x 10^(-11) N. I arrived to this answer through calculating the GPEs of both balls. Bjorn's ball has a GPE of 1.402 x 10^(-11) N. Billie Jean's ball has a GPE of <span>2.503 x 10^(-11) N. I subtracted the two and I found that Billie Jean's tennis ball has a GPE of 1.01 x 10^(-11) more than Bjorn's tennis ball.</span>
