Answer:
Induced emf,
Explanation:
It is given that,
Radius of the circular loop, r = 10.9 cm = 0.109 m
Magnetic field, B = 0.797 T
When released, the radius of the loop starts to shrink at an instantaneous rate of 107 cm/s,
Due to change in loop of the loop, an emf is induced in the loop. It is given by :
= magnetic flux
So, the emf is induced in the loop at that instant is 0.584 volts. Hence, this is the required solution.
Answer:
True
Explanation:
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. You are changing light or dark
Answer:
b.

Answer:
= -8πx
Explanation:
If you need calculate
You can use the Ampere's Law
= μ
Where : Current passing through the window
μ : Free space’s magnetic permeability
μ = 4πx
Then
= (3-5)4πx
= -8πx
