Hello, my name is Ronnie and I need help with a project im doing for DC class,

Heres a picture of the schematic:

I need help with the varibles which are:
Q=After sw-1 is closed for 1 minute what is R1 and R1?
A= R1:____Ohms
R2:____Ohms
Q=When the capictor is switched on, what is the time constant?
A=Tc_____seconds

Q= After sw-2 has been closed for 8 seconds, what will be the voltage, ec, across the capacitor?
A=Ec______volts

Q=what is the voltage E3 across the three ohm resistor?
A= E3_______Volts

Q= What is the approximate final total Power for the entire circut?
A= PT_________watts

Q=What is the total circuit resistance?
A= Rt__________ohms

Thanks alot in advance!!

 

Looks like this should be in the Homework section.
