An object is hanging by a string from the ceiling of an elevator. The elevator is moving upward with a constant speed. What is the magnitude of the tension in the string? The magnitude of the tension in the string is equal to the magnitude of the weight of the object. The magnitude of the tension in the string is less than the magnitude of the weight of the object. The tension in the string cannot be determined without knowing...

An object moves in a circular path with constant angular speed. Compare the direction of the object's tangential velocity vector to its centripetal acceleration vector. A) Both vectors point in the same direction B) The vectors point in opposite directions C) The vectors are perpendicular D) Impossible. The acceleration is zero. Two objects with masses m1 and m2 are original a distance r apart. The magnitude of the gravitational force between them is F. if BOTH masses are doubled, and...

2. A cube and a wedge with masses m1-5.00 kg and m2 10.0 kg are arranged as shown to the right. 9 There is no friction between the masses and there is no friction between the wedge and the floor. The masses are released from rest and the wedge moves to the left while the cube moves to the right. The masses only move up/down and left/right. They do not move into or out of the page. After release, the...
