Rank the pictures from right (+) net force greatest to least, then zero net force, and finally from left (-) net force least to greatest. Assume each person pushes with exactly the same force (say 100 N). Does the net force depend on the amount of mass in cart? A. B. C. D. E. Multiple Choice (4 points) In the diagram above, there is a rocket leaving the Earth and traveling to the Moon. Using the web site tutorial, choose the correct multiple choice response. 1. When the rocket is halfway between the Earth and the Moon, the force of gravity due to Earth is ____ the force of gravity due to the Moon. a. equal to b. about 10 times stronger than c. about 100 times stronger than 2. The rocket must be ____ the distance from the Moon (compared to the distance from Earth) for the forces of gravity due to the Moon and Earth be equal. a. half b. one-tenth c. one-hundredth d. double 3. When the rocket is on the Earth, the force due to the Moon is ___. a. twice as big as the Earth b. one-hundredth smaller than Earth c. one-tenth smaller than Earth d. completely negligible 4. When the rocket is on the Moon, the force due to the Earth is ____. a. twice as big as the Moon b. one-hundredth smaller than Moon Ranking Tasks (10 points) Rank each diagram by acceleration of the cart. Rank the pictures from right (+) acceleration greatest to least, then zero, and finally from left (-) acceleration least to greatest. Assume each person pushes with exactly the same force (say 100 N). Does the acceleration depend on the amount of mass in cart? A. B. C. D. E.

APA format/ 2 pages In a two-page paper, identify the classical physics principles contained within the following scenario. Explain how these principals connect to work done by Galileo or Newton. Finally, consider the different fields in which Galileo and Newton did research, and give an example of one of these fields in use in your life. For instance, Newton developed the field of optics. If you wear glasses or contact lenses, you are using Newton's physical optics theories every day. Aside from glasses or contacts, how do the theories of Newton or Galileo affect you in your daily life?
Think about how astronomers have come to the conclusion that the Big Bang theory is how the Universe began and developed. In a 2 to 3 paragraph essay, explain what Olbers' Paradox is and describe one example of observation evidence that supports the Big Bang Theory over an infinite, ageless Universe.
In your frame, a certain galaxy is moving at a high speed in the x-direction. Relative to the galaxy, a certain comet in the galaxy is also moving at a high speed in the x-direction. Let a be the galaxy’s speed with respect to you, b be the comet’s speed with respect to the galaxy, and c be the comet’s speed with respect to you. Then Select one: a. a + b > c b. a + b < c c. a + b = c d. a 2 + b 2 = c 2
