Answer» Given: A complex CIRCUIT consisting of capacitors have been provided. To find: The EQUIVALENT capacitance in between TERMINALS A and B? Calculation: In this kind of complex circuits we first need to to designate potential drops ALONG each capacitor and then try to simplify the circuit using the following tool : Capacitors which same potential drop will be considered in parallel combination. Now, refer to the attached image to understand the designation of potential drops and the simplified circuit: Now, all the capacitors have capacitance of $4\mu F$ . Now, the simplified circuit can be CALCULATED in series combination in each branch ( see 3rd diagram). Finally all the branches are in parallel. $\sf \therefore \: C_{eq} = C_{1} + C_{2} + C_{3}$ $\sf \implies \: C_{eq} =4 + 2 + 2$ $\sf \implies \: C_{eq} =8 \: \mu F$ Hope It Helps.

To find:

The EQUIVALENT capacitance in between TERMINALS A and B?

Calculation:

In this kind of complex circuits we first need to to designate potential drops ALONG each capacitor and then try to simplify the circuit using the following tool :

Capacitors which same potential drop will be considered in parallel combination.

Now, refer to the attached image to understand the designation of potential drops and the simplified circuit:

Now, all the capacitors have capacitance of $4\mu F$ .

Now, the simplified circuit can be CALCULATED in series combination in each branch ( see 3rd diagram).

Finally all the branches are in parallel.

Answer» The TIME is APPROXIMATELY proportional to the inverse of the TERMINAL velocity, so it's approximately proportional to Area/Mtotal = A/(Mp +Mw), where A is the area, Mp is the PARACHUTE mass and Mw is the other mass. Once Mp is MUCH bigger than Mw.
