Suppose you include an inductor in an electric circuit that includes a battery, a switch, and a lightbulb. current leaving the battery's positive terminal must flow through the switch, the inductor, and the lightbulb before returning to the battery's negative terminal. the current in this circuit increases slowly when you close the switch, and it takes the lightbulb a few seconds to become bright. why?

explanation:

so easy. just google the electromagnetic waves and it’ll pop up.

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
