Elements are made up of atoms
Answer:
0.82 m
Explanation:
We are given that
Weight,
=225 N
Length,l=5 m
d=1.1 m
We have to find the distance x for which person weighs 385 N walk on the overhanging part of the plank before it just begins to tip.
Half length=


When system in equilibrium then




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).
