4. Two masses of 3.7 kg and 5.5 kg are attached to either end of a massless rod of length 0.78 m. Compute the moment of inertia for:
a) The rod is rotated about its midpoint.
b) The rod is rotated at a point 0.15 m from the 5.5 kg mass.
c) The rod is rotated about the position of the 5.5 kg mass.

Animals respond in various ways to stimuli detected through their senses. some of these responses are stimulated by the presence of danger. which of these animal responses is the best example of a response to an immediate threat? a) a rooster crows every morning at the first sign of light. b) as something approaches an octopus, it shoots a cloud of ink. c) from late fall until spring, bears hibernate to preserve energy. reactivate d) a dog is getting hot in the sunlight, so he moves to a shaded area.

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change? work power gravitational energy chemical energy
