Question: Answer the following question given this paragraph: The hemisphere that is tilted away from the Sun is cooler because it receives less direct rays. As Earth orbits the Sun, the Northern Hemisphere goes from winter to spring, then summer and fall. The Southern Hemisphere does the opposite from summer to fall to winter to spring. When it is winter in the Northern hemisphere, it is summer in the Southern hemisphere, and vice versa. Q: The hemisphere that is tilted away from the sun is cooler because it receives less what? A:
OPTIONS:
- direct electrons
- x-rays
- pollution
- direct rays
Answer: direct rays

input: OPTIONS:
- electric
- force
- pressure
- power Now, answer this question: Answer the following question given this paragraph: Power is the rate at which energy is being transferred. Power tells you how many Joules per second of energy is being used to drive something. Thus power is simply the change in energy divided by the time. Since work is by definition the transfer of energy (in or out of a system), power is also equal to the work divided by the time. Efficiency tells you how efficient something is and gives a number between 0 and 1. If the efficiency is equal to 1, then the machine is perfectly efficient (that is all the power used to drive it goes to the out put of the machine with no energy losses). If the efficiency is zero, then all of the input power is lost in the machine and the machine can not output any energy. Q: What is the rate at which energy is being transferred called? A:
A:
output:
power
