Name: IDEB 18. Planets orbit around the sun. The force of gravity betwen the sun and the planets is A. weaker on mars than on Earth. B. stronger than the force of the planets on the sun C. not really a force, but something that bends space. D. causing them to move at a constant speed. E. related to the sun's mass. BD19. The relationship between the distance between two objects and the force of gravity is A. directly related C. linearly related exponentially related D. inversely related 20. Which statements are true for the electromagnetic force? A. is relatively stronger than the gravitational force. B. is directly related to the mass of an object C. is only an attractive force. is inversely related to the distance between objects. True/False Indicate whether the statement is true or false. If false, correct the underlined part to make the statement true. 21. The component of an orbiting satellite's velocity that is parallel to Earth's surface is its angular speed. 22. In a given 24-hour period, there are two high tides and two low tides. 23. The force of attraction between two masses depends inversely on the square of the distance between the masses. Any law that has this kind of dependence on distance is called an direct distance law. 24. If the sun were to suddenly become a white dwarf, the Earth would still orbit the sun
