Answer:
11.POWER
In physics, power is the rate of doing work. It is the amount of energy consumed per unit time. The unit of power is the joule per second (J/s), known as the watt (in honor of James Watt, the eighteenth-century developer of the steam engine).
12.KINETIC ENERGY TO POTENTIAL ENERGY
Energy stored in an object due to its position is Potential Energy. Energy that a moving object has due to its motion is Kinetic Energy.
13.252 J
The amount of potential energy is dependent upon mass and height and is found using the equation PE=m*g*h where g is the acceleration of gravity (approximated here to be 10 m/s/s). For a 50-kg sledder on top of a 4.0-meter high hill, the potential energy is 2000 Joules.
14.KINETIC ENERGY
The kinetic energy of the rolling can will be stored as potential energy in the tightly twisted rubber band -some will not be stored as the rubber band is wound, but transferred to friction (heat) and sound.
15.Elijah
Elijah or Greek form Elias was, according to the Books of Kings in the Hebrew Bible, a prophet and a miracle worker who lived in the northern kingdom of Israel during the reign of King Ahab. In 1 Kings 18, Elijah defended the worship of the Hebrew God over that of the Canaanite deity Baal.
