Apulley with a radius of 3.0 cm and a rotational inertia of 4.5 x 10–3 kg·m2 is suspended from the ceiling. a rope passes over it with a 2.0-kg block attached to one end and a 4.0-kg block attached to the other. the rope does not slip on the pulley. when the velocity of the heavier block is 2.0 m/s the total kinetic energy of the pulley and blocks is: (a) 2.0 j(b) 4.0 j(c) 14 j(d) 22 j(e) 28 j

A2.0 μf capacitor and a 4.0 μf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?
