Answer:
All of these answers are dependent upon the specific scenario, but here are some general answers.
1. An object with a greater height will have more potential energy.
2. Potential energy can be changed into kinetic energy as an object falls. It loses height (potential energy) and gains speed (kinetic energy).
3. Depends on what scenario your class had.
Answer:
12500 J = 12.5 kJ
Explanation:
Kinetic energy is the energy possessed by a moving object solely due to its motion.
You can get the K.E. of an object using the equation,
K.E. = (1/2)mv²
So you get, for ball
K.E. = (1/2)×1000×5² = 12500 J = 12.5 kJ

Answer:
(c) increase by a factor of four
Explanation:
energy = power x time, and power = resistance x current ^2. 2^2 = 4.
