The induced emf is 4.324 V.

It is given that the current in a 160 mH coil changes steadily from 22.0 A to 12.0 A in 370 ms.

We need to determine the magnitude of the induced emf.

An emf is induced in the coil when a bar magnet is pushed in and out of it.

The emf induced in a circuit is directly proportional to the time rate of change of the magnetic flux through the circuit.

Mathematically,

E=LdI/dt

Here

L = 160mH = 0.16H

I = 22A - 12A

dI = 10A

dt=0.37s

Putting values,

E=0.16*10/0.37

E=4.324 V.

Photons with the highest energy have the ____
Setler79 [48]

Answer:

D. shortest wavelength

Explanation:

Photons with the highest energy have the shortest wavelength. The shorter the wavelength, the higher the energy of a photon.

A photon is a quantity that transmits electromagnetic energy from one place to the other.

  • Gamma rays have photons that transmits the highest amount of energy.
  • The rays have the shortest wavelength and highest frequency of all electromagnetic radiations.

Energy, wavelength and frequency of a photon are connected using the expression:

    E =  h f  = \frac{hc}{wavelength}  

E is the energy

h is the Planck's constant

 f is the frequency.

What causes long sightedness?how is it corrected.
NNADVOKAT [17]

Answer:

Long sight occurs when the eyeball is too short or the lens is too thin, or both. As a result, light rays from near objects are focused behind the retina because the light rays are not converged enough. The image formed on the retina is therefore out of focus.

To correct this problem, people can wear glasses with convex lenses. Light rays from near objects are converged by the convex lenses before entering the eyes, so that light can be focused on the retina to form a sharp image. Additionally, long sight can also be corrected by surgical methods such as LASIK.

Summerize how friction and inertia act on an object sliding on a flat surface
natta225 [31]
Inertia is when a object in motion will stay in motion or in a standing still state unless acted upon by a unbalancing force.
Friction is when a object slows down because it is rubbing against another object.

If a object is sliding across a surface, theoretically, it would not stop but because it is on a flat surface it would experience friction, this will disperse some of the kinetic energy that it has thus slowing the object down eventually, after some time, to a stop.

Hope this helps! :)
