a paraellel plate capacitor consists of 2 large circular sheets of metal separated by 1.53 cm. The electric field energy density betwwen plates is 4.41 J/m3 while the capacitor holds .127 J of potential energy. What is the radius of the circular platyes?

The radius of the circular plate is 0.774 m

Explanation:

Given;

distance between the parallel plates, d = 1.53 cm = 0.0153 m

electric field energy density between plates,  = 4.41 J/m³

Potential energy of the capacitor, = 0.127 J

Energy density is given as;

where;

V is volume

Volume is given as;

V = Ad

where;

A is area

A = V / d

A = (0.0288) / (0.0153)

A = 1.882 m²

Area of circular plate is given as;

A = πr²

where;

r is the radius of the circular plate

Therefore, the radius of the circular plate is 0.774 m

answer: he got 23

explanation:

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
