Hi there I am really hoping a Physics tutor could support me in questions 1-17 for circular motion. I really could use the extra help so anything works please and thank you!

1. An object in circular motion travels a distance of in one revolution. 2. According to Newton's law of universal gravitation, the force of attraction between any two masses is directly related to and inversely related to 3. Which has the greater linear speed, a child near the outside of a merry-go-round or a child near the inside? 4. A ball on a string is moving around the circle as shown below. Draw an arrow to show the direction the ball would fly if the string broke when the ball was in the current position? 5. For an object moving with circular motion, the direction of centripetal acceleration is in which direction? 6. What force(s) cause(s) a mass whirled on the end of a string to move in a circle? 7. Water is in the bottom of a tin can that is being whirled horizontally on the end of a string. Since the water, like the can, moves in a circle, there must be a force on it. What is the name of this force? 8. In diagram A below, if object A's mass is doubled, how would the force be effected? 9. In diagram B below, if object B's mass is decreased by 1/4, how would the velocity be effected? 2 m m A B T =.5s T = .5s10. In diagram A below, if object A's radius is doubled, how would the acceleration be effected? 11. In the diagram below, if object B's period is tripled, how would the force be effected? 1 m m A B T = .8s T = .25s Questions 13-16: Circle the correct answer 13. The gravitational force on a ball decreases / increases as the ball moves closer to the earth. 14. The moon effects ocean tides more / less that the sun. 15. If the earth were its present volume but twice as massive, we would weigh more / less. 16. What would happen to the magnitude of the gravitational force between two bodies if: a) the mass of both of the bodies were halved (2 times smaller)? Fo= Mimz F is 4 x bigger ( x ) 2 1 x 1/ 4 b) the distance between the two bodies was halved (2 times smaller)? c) the mass of both of the bodies were doubled, while the distance between the two bodies were reduced 3 times? Fo = GMim2 Fis 36x bigger ( # r) 2 Pp 17. What provides the centripetal force that keeps a satellite in orbit
