A bungee jumper is standing at the edge of a platform, just about to leap over the side. Midway through the jump, while the bungee jumper is halfway down to the ground, what is the relationship between potential and kinetic energy? There is only kinetic energy at this point.
Potential energy has decreased, and kinetic energy has increased.
Potential and kinetic energy are both zero.
Kinetic energy has decreased, and potential energy has increased.

There is only kinetic energy at this point.

Potential energy has decreased, and kinetic energy has increased.

Potential and kinetic energy are both zero.

Kinetic energy has decreased, and potential energy has increased.

c is the answer because when something is left after something evaporates that shows the chemical change.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
