Ques: Answer the following question given this paragraph: Figure 34.12 (a) Light from a distant galaxy can travel different paths to the Earth because it is bent around an intermediary galaxy by gravity. This produces several images of the more distant galaxy. (b) The images around the central galaxy are produced by gravitational lensing. Each image has the same spectrum and a larger red shift than the intermediary. (credit: NASA, ESA, and STScI). Q: Light from a distant galaxy can travel different paths to the earth because it is bent around an intermediary galaxy by what? Choices: - radiation - strength - variation - gravity A:
Ans: gravity
(Q).
Answer the following question given this paragraph: gravitational potential energy. Making Connections: Power Power is defined as the rate of energy transferred, or E / t . Fluid flow involves several types of power. Each type of power is identified with a specific type of energy being expended or changed in form. Q: What is defined as the rate of energy transferred? Choices: - charge - capacity - pressure - power A:
(A).
power

Ques:Answer the following question given this paragraph: Earth's magnetic poles have switched places repeatedly in the past. As you can see in the Figure below , each time the switch occurred, Earth's magnetic field was reversed. The magnetic field is the region around a magnet over which it exerts magnetic force. We think of today's magnetic field direction as "normal," but that's only because it's what we're used to. You can watch a simulation of a magnetic field reversal at this URL: http://www. pbs. org/wgbh/nova/earth/when-our-magnetic-field-flips. html. Q: The earth's magnetic poles have done what repeatedly in the past? Choices: - rotated - stayed the same - demagnetized - switched places A:

Ans:
switched places
