How far apart are two conducting plates that have an electric field strength of 8.53 x 103 V/m between them, if their potential
sleet_krkn [62]

Answer:

d=2.7m

Explanation:

From the question we are told that:

Electric Field strength E=8.53 * 10^3 V/m

Potential difference is V= 23.0 kV

Generally the equation for distance is mathematically given by

d=\frac{V}{E}

d=\frac{23.0*10^3}{8.53 * 10^3 V/m}

d=2.7m

Which two surfaces have the lowest coefficient of friction
jok3333 [9.3K]

Answer:

Explanation:

As an example, ice on steel has a low coefficient of friction – the two materials slide past each other easily – while rubber on pavement has a high coefficient of friction – the materials do not slide past each other easily. The coefficients of friction ranges from near 0 to greater than 1.

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).
