Bar OC rotates with a clockwise angular velocity ωOC = 4.3 rad/s and a counterclockwise angular acceleration αOC = 2.3 rad/s2. The bar OC is a slotted member which accommodates the pin A attached to the sector. Determine the angular velocity ω and the angular acceleration α of the sector. The angular velocity and the angular acceleration are positive if counterclockwise, negative if clockwise.

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
