A 28.2 g sample of nickel is heated to 99.8oC and placed in a coffee- cup calorimeter containing 150.0 g of water at a temperature of 23.5oC. After the metal cools, the final temperature of metal and water is 25.0oC. Calculate the heat capacity of nickel, assuming that no heat escapes to the surroundings or is transferred to the calorimeter.

Write maxwell's equations and discuss the terms involved and the results of each equation in classical electrodynamics. if it is possible to write these equations in integral form, give the integral forms. find the wave equation for electromagnetic waves from the maxwell equations. what is the propagation velocity of electromagnetic waves in space according to the wave equation you find?
