Alight spring with a force coefficient 10.83 n/m is compressed by 12.7 cm as it is held between a 0.29 kg block on the left and a 0.79 kg block on the right, both resting on a horizontal surface. the spring exerts a force on each of the blocks, tending to push them apart. the blocks are then released from rest.

find the acceleration of each block if the coefficient of friction between the blocks and the surface is:

[note: this question may require you to perform your calculations to a few extra digits of precision to get the answer to within 1%.]

(a) μ = 0: right

(b) μ = 0.158: right

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

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
