Suppose you have a 34.9 m length of copper wire. If the wire is wrapped into a solenoid 0.240 m long and having a radius of 0.05

Nadusha1986 [10]

Answer:

the strength of the magnetic field inside the solenoid is 6.278 x 10⁻³ T.

Explanation:

Given;

length of the wire, = 34.9 m

length of solenoid, L = 0.24 m

radius of the solenoid, r = 0.051 m

current in the solenoid, I = 11.0 A

The number of turns of the wire is calculated as follow;

$N = \frac{34.9}{2\pi \times 0.051} = 109 \ turns$

The strength of the magnetic field inside the solenoid is calculated as follows;

$B = \mu_0 (\frac{N}{L} )I\\\\B = 4\pi \times 10^{-7} \times (\frac{109}{0.24} )\times 11.0 \\\\B = 6.278 \times 10^{-3} \ T$

Therefore, the strength of the magnetic field inside the solenoid is 6.278 x 10⁻³ T.

Write the advantages and disadvantages of Friction ?

pickupchik [31]

<h2>★ « advantages » ★</h2>

Friction enables us to walk freely.
It becomes possible to transfer one form of energy to another.
It helps to support ladder against wall
Objects can be piled up without slipping.

<h2>★ « disadvantages » ★</h2>

Friction produces a lot of heat in various parts of the machinery and this leads to wastage of energy as heat.

Opposes motion, hence more energy is needed to overcome friction.

Noise production in machines is irritating as well as leads to energy loss.

<h2>hope it helps!</h2>
