The period and radius of the orbits of satellites a Mathway I Math Problem Solver Introduction to Newtonian Mechanics | Independe Final Quiz Lesson 13 Physics 121 1, An object weighs slightly less on mountain peak than near the base of the same peak. This is primarily because a the peak is slightly further from the Earth's center, thus g is slightly less there. b the centripetal force on the object, which is a consequence of the rotation of the Earth, is slightly greater on the peak than at lower elevations. heavenly bodies, such as the sun and the moon attract the object most strongly when it is at a peak. the downward pressure of the Earth's atmosphere is less at the top of the peak than at the base. c. d, The following scenario applies to problems 2-4: We have two masses attracting each other due to their mutual gravitation. We double both masses and move them three times farther apart from each other 2 In this case, the gravitational force between thern will be multiplied by a factor of a 2/3 b. 29 . 43 d. 9 e. f. 18 E 36 3 In this case the gravitational potential energy between them will be multiplied by a factor of a 43 b. 29 C. 23 d. 9 e. f. 18 E 36 4. Will it take more or less work to separate the two masses out to infinity after the change has been made? a. It will take more work to scparate the two masses after the changc. b. It will take less work to separate the two masscs after the change. c. It will take the same amount of work to separate the two masses. d. Nt enough information is given to decide.Explanation / Answer
1) a
2) d
Fnew= G (2m1) (2m2) / (3r)2 = 4/9 F
3) a
PEnew = G (2m1) (2m2) / (3r) = 4/3 PE
4) a
5) b
