PLEASE HELP ME!! Larry plans to connect the opposite ends of a coiled wire to a 10 W lightbulb
to make the bulb light up. What must he also do to induce an electric current
in the wire?
A. Move a small electromagnet around the lightbulb continuously
until the bulb lights up.
B. Move a small magnet back and forth within a section of the coiled
wire.
C. Move the lightbulb and the coiled wire around a magnet until the
bulb lights up.
D. Move the lightbulb so that several of the coils in the wire wrap
around the bulb.

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
