Answer:
The average induced emf in the loop is 0.20 V
Explanation:
Given:
Radius of loop
m
Magnetic field
T
Change in time
sec
According to the faraday's law,
Induced emf is given by

Where
magnetic flux
( here
)
Where 
We neglect minus sign because it's shows lenz law


V
Therefore, the average induced emf in the loop is 0.20 V
The hypotenuse is measured at 120 meters of string, and you need to solve for the leg of the triangle that is horizontal. The degree is 40, so use trigonometry to figure it out.
Cosin (40) is equal to around .766
Adjacent/Hypotenuse
x/120 = cos40
Answer: 91.92533.
If you use 3 significant figures it should be 91.9 meters.
