A1300-turn coil of wire that is 2.10 cm in diameter is in a magnetic field that drops from 0.130 t to 0 t in 12.0 ms. the axis of the coil is parallel to the field.
question: what is the emf of the coil? (in v)

4.875 V

Explanation:

N = 1300

diameter = 2.10 cm

radius = half of diameter = 1.05 cm

B1 = 0.130 T

B2 = 0 T

t = 12 ms

According to the law of electromagnetic induction,

Where, Ф be the magnetic flux linked with the coil

e = 4.875 V

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
