A flask has a base of radius 12 cm and narrows to a neck of radius 6 cm. It’s filled to the base of the neck with water. If 5.5x10-4 m3 of additional water is poured into the flask, by how much does the force of the water on the base increase?

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
