The magnitude of the frictional force of the box is 65 N

From the question given above, the following data were obtained:

  • Mass (m) = 25 Kg
  • Force applied (Fₐ) = 135 N
  • Net force (Fₙ) = 70 N
  • Frictional force (Fբ) =?

The frictional force acting on the box can be obtained as follow:

Fₙ = Fₐ – Fբ

70 = 135 – Fբ

Collect like terms

70 – 135 = – Fբ

–65 = –Fբ

Multiply through by –1

<h3>Fբ = 65 N</h3>

Thus, the frictional force of the box is 65 N

A device that uses electromagnetic induction to transfer electrical energy from one circuit to another is a(n)_____.
Nutka1998 [239]

A device that uses electromagnetic induction to transfer electrical energy from one circuit to another is a transformer.

<h3>Which device uses electromagnetic induction to transfer electrical energy from one circuit to another?</h3>

  • A transformer is an electrical device that transfers energy from one electric circuit to another using the electromagnetic induction principle.
  • It is intended to change the AC voltage between the circuits while keeping the current's frequency constant.
  • A transformer work on the principle of electromagnetic induction in which flux is linked from primary to secondary.
  • Transformers accomplish this without establishing a conductive link between the two circuits. This is made feasible by using Faraday's Law of Induction, which explains how an electric circuit will interact with a magnetic field to produce an electromotive force (EMF).
