While visiting White Sands National Park, you grab a piece of cardboard box and slide down a large sand dune from the top of the dune to the bottom of the dune. Friction is present; air resistance can be ignored. Which statement correctly describes the change in energy as you slide from the top of the dune to the bottom of the dune on the cardboard box? AThe sum of the kinetic energy and the gravitational potential energy changesby an amount equal to the energy dissipated by friction. BThe gravitational potential energy decreases, and the kinetic energy isconstant. CThe decrease in the gravitational potential energy is equal to the increase inkinetic energy. DThe gravitational potential energy and the kinetic energy must bothdecrease.

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.

What is the magnitude of the resultant vector round your answer to the nearest tenth

In a set amount of time, a battery supplies 25j of energy to an electric circuit that includes two different loads. one of the loads produces 10 j of heat energy during this time interval. how much heat energy is produced by the second load in this time? explain your answer
