A solenoid of 2100 turns, area 10 cm2, and length 30 cm carries a current of 4.0 A. (a) Calculate the magnetic energy stored in

nikitadnepr [17]

Answer:

E = 0.1472 J

Explanation:

Given that,

The number of turns in the solenoid, N = 2100

Area of the solenoid, A = 10 cm² = 0.001 m²

The length of the solenoid, l = 30 cm = 0.3 m

Current in the solenoid, I = 4 A

We need to find the magnetic energy stored in the solenoid. The expression for the stored energy is :

$E=\dfrac{1}{2}LI^2$

Where

L is self inductance of the solenoid,

$L=\dfrac{\mu_oN^2A}{l}\\\\L=\dfrac{4\pi \times 10^{-7}\times 2100^2\times 0.001}{0.3}\\\\L=0.0184\ H$

So,

$E=\dfrac{1}{2}\times 0.0184\times 4^2\\\\E=0.1472\ J$

So, 0.1472 J of energy is stored in the solenoid.

How long is a string under 240 N of tension whose mass is 0.086 kg if a wave travels through it at a speed of 12 m/s?

Darina [25.2K]

Answer:

The length of the string is 0.051 meters

Explanation:

It is given that,

Tension in the string, T = 240 N

Mass of the string, m = 0.086 kg

Speed of the wave, v = 12 m/s

The speed of the wave on the string is given by :

$v=\sqrt{\dfrac{T}{M}}$

M is the mass per unit length of the string i.e. M = m/l.......(1)

So, $M=\dfrac{T}{v^2}$

$M=\dfrac{240\ N}{(12\ m/s)^2}$

M = 1.67 kg/m

The length of the string can be calculated using equation (1) :

$l=\dfrac{m}{M}$

$l=\dfrac{0.086\ kg}{1.67\ kg/m}$

l = 0.051 m

So, the length of the string is 0.051 meters. Hence, this is the required solution.
