A current-carrying wire with many loops is called solenoid.

<u>Explanation:</u>

A current-carrying wire is a conductor. When it is turned into a coil for better use, it is called a solenoid. A solenoid has specific features. Since it is wrapped up in many turns, it creates a magnetic field inside. They also convert electric current into mechanical work or action.

The solenoid may or may not be straight. Anything wrapped into a coil is a solenoid. While the study, the length of a solenoid is taken greater than the diameter. And the shape is called a helix.

Answer:

Explanation:

extension in the spring = 40.4 - 31.8 = 8.6 cm = 8.6 x 10⁻² m .

kx = mg

k is spring constant , x is extension , m is mass

k x 8.6 x 10⁻² = 7.52 x 9.8

k = 856.93 N/m

= 857 x 10⁻³ KN /m

b ) Both side is pulled by force of 188 N .

Tension in spring = 188N

kx = T

856.93 x = 188

x = .219.38 m

= 21.938 cm

= 21.9 cm .

length of spring = 31.8 + 21.9

= 53.7 cm .

If it requires 7.0 j of work to stretch a particular spring by 2.1 cm from its equilibrium length, how much more work will be re

4.6 j more. To get this take 7 and multiply it by 3.5 to get 24.5 take the x which is what you’re looking for and multiply it by the 2.1 to get 2.1x. Take 24.5 and divide it by 2.1 x and get 11.6. Subtract 11.6 by 7 and get 4.6
