When two capacitors are connected in parallel and then connected to a battery, the total stored energy is 6.9 times greater than
when they are connected in series and then connected to the same battery.
What is the ratio of the two capacitances? (Before the battery is connected in each case, the capacitors are fully discharged.)

Answer:
11.6mph South East
Explanation:
Given parameters:
Time = 2.25hrs
Displacement = 26.2miles south east
Unknown:
Velocity = ?
Solution:
Velocity is the displacement divided by the time taken. It is a vector quantity with both magnitude and direction.
Now;
Velocity =
Velocity = = 11.6mph South East
