Answer:

D) Spinning a coil of wire near a large magnet.

Explanation:

From Faraday's law of induction, when a conducting coil of wire is placed in changing magnetic flux, an emf is induced which produces current in the coil.

Induced emf is given by:

e = -\frac{d\phi}{dt}

A generator is based on the same principle.

The mechanical energy of rotating coil is converted to electrical energy when current is induced. Thus, the correct option is D) Spinning a coil of wire near a large magnet.

Which of the following distinguishes electromagnetic waves from mechanical waves
Ivan

Answer:

Explanation:

1. Mechanical waves require material medium for their propagation while electromagnetic waves do not require material medium for their propagation.

2. Mechanical waves can either be transverse or longitudinal while electromagnetic waves are transverse.(Transverse waves are waves in which the vibration of the particules of the medium is perpendicular to the direction of the motion of wave. E.g water waves, waves of a plucked string and all electromagnetic waves RIVUXG . Longitudinal waves are waves whose vibration are parallel to the direction of the motion of the medium e.g waves in strings, sound waves.e.t.c)
