After the switch in the circuit of Fig. P 7.35 has been open for a long time, it is closed at t=0. Calculate (a) the initial value of i; (b) the final value of i; (c) the time constant for t≥0; and (d) the numerical expression for i(t) when t≥0.

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.
