A generator uses a coil that has 270 turns and a 0.48-T magnetic field. The frequency of this generator is 60.0 Hz, and its emf

Musya8 [376]

Answer:

The total length of wire is 0.24 m.

Explanation:

Number of turns, N = 270

magnetic field, B = 0.48 T

frequency, f = 60 Hz

rms value of emf = 120 V

maximum value of emf, Vo = 1.414 x 120 = 169.68 V

let the area of square is A and the side is L.

The maximum emf is given by

Vo = N B A w

169.68 = 270 x 0.48 x A x 2 x 3.14 x 60

A = 3.5 x 10^-3 m^2

So,

L = 0.0589 m

Total length of wire, P = 4 L = 4 x 0.0589 = 0.24 m

If average acceleration is calculated using the equation, “change in velocity / change in time,” what is an objects acceleration

harina [27]

Answer:

Acceleration of object= $8cm/s^{2}$

Explanation:

Given:-

Velocity (v)=24 cm/s

Time (t)=3 s

To calculate acceleration (a) of object=?

Now,

$acceleration =\frac{velocity}{time}$

$a=\frac{v}{t}$

$a=\frac{24}{3}$

$a=8 cm/s^{2}$

Therefore object acceleration = $8cm/s^{2}$

What is one way that an electric field is different from a magnetic field?

liubo4ka [24]

Answer with Explanation:

Electric field:It is the force per unit charge experienced by rest charge at any given point.

It is the area around the charge which is placed at rest.It is represented by E.

Mathematical formula:

$E=\frac{F}{q}$

Magnetic field:It is an area around moving charge in which moving charge particle experienced magnetic force in that area.

Magnetic field is represented by B.

Mathematical formula :

$F=qvBsin\theta$

Where B=Magnetic field

q=Charge on particle

v=Velocity of particle

F=Magnetic force exert on particle
