Which one of the following terms is used to describe a system in which the degree of damping is just enough to stop the system from oscillating? Score: 1/1 3. A thin, circular hoop with a radius of 0.22 m is hanging on a nail. Adam notices that the hoop is oscillating back and forth through small angles like a physical pendulum. The moment of inertia of the hoop for the rotational axis passing through the nail is I = 2 mr 2 . What is the period of the hoop? Score: 0/1 4.
3 . It is then submerged below the surface of a liquid and its volume decreases to 1.96 m 3 . Reference: Ref 10-3 Complete the following statement: In order to calculate the "stress" on the box, in addition to the information given, one must also know Score: 0/1 5. A 0.2-kg block is held in place by a force F that results in a 0.10-m compression of a spring beneath the block. The spring constant is 1.0 × 10 2 N/m. Assuming the mass of the spring is negligible compared to that of the block, to what maximum height would the block rise if the force F were removed. Score:
