Which claim about the universality of gravity is not supported by evidence? * (1 Point) A. Any two objects that have mass also have a force of gravity acting between them, no matter how far apart they are. B. The gravitational force between two objects depends only on their masses. O C. The gravitational force between two objects increases if mass is added to one object. D. The gravitational force between two objects increases if the objects move closer together.​

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
