Explanation :

As the ambulance got closer, Marge noticed that the pitch of the siren got higher. This is due to the Doppler's effect.

The siren of the ambulance has a higher pitch when it approaches Marge. When the waves move away from him, it will have a lower pitch.

As the waves come closer to us, the waves become compressed and hence the frequency of the wave increases.

Answer:

The value of current generated would increase.

Explanation:

Electromagnetic induction is the process by which an electromotive force is induced due to a variation of magnetic field.

The induced current is directly proportional to rate at which the coil cuts the magnetic field. Using more powerful battery in the experiment would increase the rate at the the coil cuts the magnetic field, therefore increasing the rate of variation in the magnetic field. This effect would cause a greater deflection on the galvanometer's scale, showing an increase in the current generated.

This experiment proves that an alternating current can be produced from magnetic field.
