Problem 3:
find the amount of power that is delivered to a load at 1 = 3ms if the current entering the
positive terminal is given by the following expression for current:
i=5cos60pit
with voltages given by the expression (a) v = 3i and (b) v = 3di/dt

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
