Answer:
103.1 V
Explanation:
We are given that
Initial circumference=C=168 cm

Magnetic field,B=0.9 T
We have to find the magnitude of the emf induced in the loop after exactly time 8 s has passed since the circumference of the loop started to decrease.
Magnetic flux=
Circumference,C=

cm



When t=0



E=

t=8 s
B=0.9


<span>The mechanical advantage to simple machines is that they allow a decreased input force to create a larger output force.

I think its <u>B</u> because it looks like it might indicate a future rain storm.
