C is the right answer.
Body massager uses electrical energy to move back and forth. In this sense, a motor is being used for the operation
Answer:
Explanation:
The work done is defined as the product of force applied in the direction of displacement and the displacement.
W = F x d x Cosθ
where, F is the force applied, d be the displacement and θ be the angle between the displacement and force.
For the normal forces, the angle between the displacement and the force applied is 90 degree, and the value of Cos 90 is zero, so the work done is zero.
It is actually are tools that make work easier C because i just had it on study island
