How does electromagnetic induction in a moving loop of wire cause an electric generator to produce an electric current?
A. Mechanical energy flows out of the magnets and into the electric
charges in the loop of wire.
B. Charged particles flow within the wire because they are pushed by
the magnetic field of the magnets.
C. Charged particles flow when the loop of wire is attracted by the
magnetic field of the magnets.
O D. Electrons flow from the magnets into the loop of wire and
continue to flow within the wire.

B. Charged particles flow within the wire because they are pushed by

the magnetic field of the magnets.

Explanation: took the quiz on a pe  x

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
