Consider two wheels with fixed hubs. the hub cannot move, but the wheel can rotate about it. the hubs are fixed to a stationary object. the hubs and spokes are massless, so that the moment of inertia of each wheel is given by i = mr2 , where r is the radius of the wheel. each wheel starts from rest and has a force applied tangentially at its rim. wheel a has a mass of 1.0 kg, a diameter of 1.0 m, and an applied force of 1.0 n. wheel b has a mass of 1.0 kg and a diameter of 2.0 m. the two wheels undergo identical angular accelerations. what is the magnitude of the force applied to wheel b?

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ

Individuals who live below the poverty line get seriously ill more often than those who do not what could be the hidden variable in this situation?

Cathy is pedaling down a steep hill on her bicycle and wants to be able to coast up the next hill, which is 25 meters high, without pedaling. cathy and her bicycle have a mass of 75 kg. assuming her bicycle is 100% efficient, what would her speed have to be?
