hello i need help and show work please thank you

In the the Figure. given R=574KQ. C=19.5|.|.F, and V=13.9V. The switch has been open for along time for an uncharged capacitor. Find the time constant {unit in second) of the circuit. In the the Figure. given R=393KQ C=37.1pF, and V=22.4V. The switch has been open for a long time for an uncharged capacitor. It is then suddenlyr closed. Find the maximum charge {unit in will on the capacitor. In the the Figure. given R=272KQ C=86.1pF, and V=14.6V. The switch has been open for a long time for an uncharged capacitor. It is then suddenly closed. Find the charge {unit in pC) on the capacitor one time constant after the switch is closed. In the the Figure. given R=591KQ C=36.5uF, and V=23.1V. The switch has been open fora long time for an uncharged capacitor. It is then suddenly closed. How long (unit in second) does it take the charge on the capacitor to increase to 63% its initial value? In the the Figure. given R=593KQ C=20.4pF, and V=15.6V. The switch has been open fora long time for an uncharged capacitor. It is then suddenly closed. Find the charge (unit in MC} on the capacitor ten time constant after the switch is closed. In the the Figure. given R=725KQ C=30.3|.1F, and V=30.2V. The switch has been open for a long time for an uncharged capacitor. It is then suddenly closed. Find the voltage across the resistor (unit in V) at the moment after the switch is closed one time constant. In the the Figure, given R=428KQ, C=16.2pF, and V=34.5V. The switch has been open for a long time for an R uncharged capacitor. It is then suddenly closed. Find the V C current passing through the resistor (unit in HA) at the moment after the switch is closed one time constant
