How do i solve the attached physics question?
![Part A
You're designing an external defibrillator that
discharges a capacitor through the patient's body,
providing a pulse that stops ventricular fibrillation.
Specifications call for a capacitor storing 250 J of
energy; when discharged through a body with 39-N
transthoracic resistance, the capacitor voltage is to
drop to half its initial value in 10 ms.
Determine the capacitance (to the nearest 10 µF).
Express your answer with the appropriate units.
