#7) The famous Leaning Tower of Pisa doesn't topple over because its center of gravity is Aj displaced from its canter. B) stabilized by its structure. C above a place of support. Dj irelatively low for such a tall building [E) In the same place as its cantor of mins. ") A difference between linear momentum and angular momentum involves Aj two types of speed. B B radial distance. C both of these Dy neither of there "j A ring, a disk, and a solid sphere begin rolling down a hill togather. Which reaches the bottom Aj all reach the bottom at the same time Bi dick C ring [CQ sphere [Ej ineed more information 45) As a hugs rotaling cloud of parilices in space gravitate together forming an increasingly dense ball, in shrinks in size and Aj rotates at the same speed. B) rotates inter. D) rotates slower. #8) If you place a pipe over the end of a wrench when trying to rotate a stubborn bolt, effectively making the wrench handle twice as long you'll multiply the tongue by Aj night. By four. #7) On each given day and location, tides rise and fall at A) different times. B) coactly the same time. Q ever incmining rates daily. Do about the same line. "80 According to Newton, when the distance between two interacting objects doubles, the gravitational Aj twice as much. Bj the same IDj four times as much. E) one-quarter. "#7) If the Sun collapsed to a black hole, Earth's gravitational attraction to it would be Aj IBE By the same. C) mora 100) A black hole is Aj an empty region of space with a huge gravitational field. Bj the remains of a giant star that has undergone gravitational collapse. 3) at the center if all starsto1) We do not observe tides in a community swimming pool became Aj It is shallow compared to the ocean. Bj the tides are only observed at night. Call paris of it are practically the same distance from the Moon. Do gravitation on the small mass of water is inagligibly small. E) they are manked by the much stronger pull of Earth gravity. 1:02) The main reason opsan tides exist is that Moon's pull is stronger Aj on water closer to if than on water farther away. Bj on Earth's tocoma than on Earth itself. C) than the pull of the Sun. Dj all of the above 103) Passengers in a high-flying jumbo jet food their normal weight in flight, while passangers in an orbiting space while do not, because pansangers in the space which are Aj above Earth's atmosphere. Bj without support forces beyond the main pull of Earth's gravity. Dj all of the above E) inone of the above Aj in the absence of a supporting surface. B) in a freely falling elevator. C momantarily when you step off a chair. D) all of the above 105) A bullet fired horizontally from a rifle begins to fall Aj after air friction reduces its speed. B) as soon as it leaves the barrel. 9 neither of these 108) Two projectiles are fired from ground level at equal spooks but different angles One is fired at an angle of 30" and the other at 60'. Naglacting air iresistance, the projectile to hit the ground first will be the one fired at Aj W. B) both hit at the same time for According to Kepler, the orbital period of a planet is directly proportional to the Aj plmel's average distance from the Sun. Bj cube of the planet's average distance from the Sun. C square of the planet's average distance from the Sun. 108) Angular momentum is conserved for a satellite in Aj circular orbit Bj elliptical orbit C) both off these Of neither of there 10%j While a rock thrown upward at 50 degrees to the horizontal rises, naglacting air drag, its vertical Component of velocity C remains unchanged
