Find the work WWW done by the 18-newton force. Use two significant figures in your answer. Express your answer in joules.

W = (18) d

W = 18 d

Now, this is the work done by 18 N force in Joules. Here, d is the value of displacement that occurs due to the force.

If we assume a distance of 1 m, then work done will be:

W = (18 N)(1 m)

W = 18 J

Explanation:

Work is said to be done when a force is applied to an object. And the object displaced by some distance as a result of the applied force. Hence, the formula for the work done is given as follows:

W = F d Cosθ

where,

W = Work Done

F = Force Applied

d = displacement

θ = Angle between force and displacement

We are given a force of 18 N. So, in order to find the work done we first assume that the force and displacement are in same direction (θ = 0°).

W = (18) d

W = 18 d

Now, this is the work done by 18 N force in Joules. Here, d is the value of displacement that occurs due to the force.

If we assume a distance of 1 m, then work done will be:

W = (18 N)(1 m)

W = 18 J

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
