Now strike the tuning fork on the rubber stopper and slowly place it in the water in the cup. What happened? What caused this reaction? What property of sound does this demonstrate?

find the sum of the two horizontal vectors and the sum of the two vertical vectors

isoceles right angled triangle

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
