What is the de broglie wavelength of a bullet of mass 0.02500 kg traveling at 450.0 m/s

Determine the amount of work done when a crane lifts a 100-n block form 2m above the ground to 6m above the ground

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

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
