Answer:

In summary kinetic energy is not necessary

Explanation:

In this problem we are asked to indicate what type of energy does not need to be considered.

As they indicate that the masses do not move, scientific energy is defined by

      K = ½ m v²

Since the velocities of the mass are zero, this energy is zero, so it is not necessary to take them into account in our analyzes.

In summary kinetic energy is not necessary

olga nikolaevna [1]

Answer:

B)

The magnitude of induced emf in the conducting loop is 0.99 mV.

Explanation:

Rate of increase in magnetic field per unit time = 0.090 T/s

Area of the conducting loop = 110 cm^2 = 0.0110 m^2

Electromagnetic induction is the production of an emf or voltage in a coil of wire due to a changing magnetic field through the coil.

Induced e.m.f is given as:

EMF = (-N*change in magnetic field/time)*Area

EMF = rate of change of magnetic field per unit time * Area

EMF = 0.090 * 0.0110

EMF = 0.00099 V

EMF = 0.99 mV
