A solenoid with 500 turns, 0.10 m long, carrying a current of 4.0 A and with a radius of 10-2 m will have what strength magnetic

lakkis [162]

Answer:

Therefore,

Strength magnetic field at its center, B

$B = 2.51\times 10^{-2}\ T$

Explanation:

Given:

Turn = N = 500

length of solenoid = l = 0.10 m

Current, I = 4.0 A

Radius, r = 0.01 m

To Find:

Strength magnetic field at its center, B = ?

Solution:

If N is the number of turns in the length, the total current through the rectangle is NI. Therefore, Ampere’s law applied to this path gives

$\int\ {B} \, ds = Bl=\mu_{0}NI$

Where,

B = Strength of magnetic field

l = Length of solenoid

N = Number of turns

I = Current

$\mu_{0}=Permeability\ in\ free\ space = 4\pi\times 10^{-7}\ Tm/A$

Therefore,

$B =\dfrac{\mu_{0}NI}{l}$

Substituting the values we get

$B =\dfrac{4\times 3.14\times 10^{-7}\times 500\times 4}{0.10}=2.51\times 10^{-2}\ T$

Therefore,

Strength magnetic field at its center, B

$B = 2.51\times 10^{-2}\ T$

What feature is the result of a glacier carving out rock as it moves?

Flauer [41]

<span>A Roche Moutonnee is formed as a result of a glacier carving out rock as its moves. This rock hill has a smooth up-ice side and a rough down-ice side. The smooth up-ice side is the side where the glaciers passed. The rough down-ice side is the side where ice melts slightly by pressure and seeps down on the rocks, when the water refreezes, the ice becomes attached to the rocks connecting it to the glacier. Thus, when the glacier moves, pieces of the rocks are stripped from the rock formation leaving an uneven rough side. </span>

on a distant planet a freely falling object has an acceleration of 20 m/s.^2 what speed will a body dropped from rest on his pla

N76 [4]

Answer:

30 m/s

Explanation:

Vf = ?

Vi = 0 m/s

a = 20 m/s^2

t = 1.5 s

Plug those values into the equation: Vf = Vi + at

Vf = 0 + (20)(1.5)

Vf = 30 m/s
