(01.05 LC)A variable that is being tested or observed by the scientist in an experiment is a(n)

(03.04 MC)A ball of mass 1.2 kg is attached to a 0.65 m long string. It is moving horizontally in a clockwise direction, 4.0 m above ground, with a speed of 22.0 m/s. The centripetal acceleration of the ball is

(02.05 LC)Finish this statement: Gravitational force between two objects depends on the

(02.02 MC)A car accelerates from 5.00 m/s to 20.0 m/s. This takes place over 50.0 meters. What is its rate of acceleration?

(03.01 MC)Two objects are being observed in space. Their data is given as follows: Object A’s mass = 6.7 E28 kg Object B’s mass = 2.4 E30 kg Distance between both objects = 2.3 E12 m Determine the gravitational force between these two objects. (G = 6.67 E−11 Nm2/kg2)

(03.07 LC)Identify the energy that can be released during fusion or fission.

(01.07 LC)A car travels 25.0 meters in the first 10.0 seconds of a trip and 40.0 meters in the next 10.0 seconds of the trip. What is the average speed of the car in meters per second for the total trip?

(01.05 LC)A variable that can be manipulated by the scientist in an experiment is a(n)

(01.05 LC)A variable that is left unchanged between various trials by the scientist in an experiment is a(n)

(02.05 MC)An object is allowed to fall freely near the surface of an unknown planet. The object falls 72 meters from rest in 4.0 seconds. The acceleration due to gravity on that planet is
