Electromagnetic induction occurs when:

A) electromagnets are induced in a wire.
B) electrons are induced in a magnet by a moving wire.
C) current is induced in a wire by a moving magnet.
D) a magnetic field is induced into a coil of wire by a magnet.

It occurs when a magnetic field is induced into a coil of wire by a magnet.

It occurs when a magnetic field is induced into a coil of wire by a magnet.

Explanation:

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
