Explanation / Answer

here

part A:

time cosnatnt T = RC (formula)

---------------------------------------------------
part B:

Time constant T = 45 * 11 *10^-6

T = 0.495 ms

------------------------------------
C.

while charging up,

Q = Qo (1 - e^-t/RC)

---------------------------------
D.

Qo is the max charge = CV

Qo = 11*10^-6 * 7.5

Qo = 82.5 uC
