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:
A final velocity that is faster than an initial velocity.
Explanation:
The acceleration of an object is given by :

Where
v is final velocity and u is initial velocity
t is time taken
If the final velocity is more than the initial velocity, the acceleration is positive. So, the correct option is (a).
Answer:

Explanation:
First of all, we need to convert the angular velocity from revolutions per second to radiands per second. We know that

So
We also know that the distance of the inner ear from the centre of the circular path is

the radial (centripetal) acceleration experienced by a point on the inner ear is

Therefore, substutiting the previous values, we find the radial acceleration of the endolymph fluid:
