What is the speed of a wave on a guitar string with a mass of 0.3 kg, with a length of 0.45 m, if the force of tension on the
string is 20N?

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
