Three students are about to dive from the high boards into the pool. The boys are on diving boards that are 3 m above the water, and the girl is on a board that is 5 m above the water. Using the picture as a model of energy levels, which of these has the MOST gravitational potential energy AND explain HOW YOU KNOW. (hint: think about what is true about things with a large potential energy…)

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?
