Why is physics used to study the heat absorbed by the ocean? A. The ocean is important.
B. Heat is a form of energy.
C. The Sun gives off heat.
D. Physicists mostly study the ocean.

B

Explanation:

It absorbs gases, but also heat energy from the atmosphere, distributes them in its depths and thus slows down changes in the entire Earth system. The amount of energy absorbed by the ocean is therefore also an indication of the total heat absorbed by the planet.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
