Which of the following best describes Young's Modulus? a) It indicates the maximum stress that a solid object can be subjected to before failing. b) It is a ratio of the strain a material experiences divided by the stress applied. c) It is the ratio of the force applied to a material divided by the stretch a material experiences. d) It indicates the maximum force a material can withstand before failing. e) It is the ratio of the force applied to deform a material divided by the strain it experiences. f) None of the above. 6. Suppose we have two, square windows that were made the exact same way except their areas are different. Window A has dimensions of 0.5m x 0.5m and window B has dimensions 1m x 1m. This will cause as much energy flow through window A as compared to window B per unit of time. a) half b) twice c) four times d) % 7. Newton's Universal Gravitation law indicates that planets with a smaller radius will always have a smaller acceleration due to gravity on their surface. a) True b) False c) Don't have enough information to determine if this statement is true or false. 8. Two bowling balls, ball A and B, are separated by 1m and are out in deep space. Such that, they are only affected by their mutual gravitational attraction. Bowling ball A has a mass of 7 kg and ball B has a mass of 6 kg. Which of the following is true? a) The bowling balls will accelerate toward each other at the same rate. b) Bowling ball A will accelerate faster toward B than B will accelerate toward A. c) Bowling ball B will accelerate faster toward A than A will accelerate toward B.
