Answer:
a. 20.01 km
b. 55.584 m/s
Explanation:
Assume there's no air resistance there. We can use the following equation of motion to calculate the distance traveled over t = 12 minutes (12 * 60 = 720 seconds):
And the speed with it hits the bottom
The solution for the questions below is mathematically given as
- induced emf=0
- induced emf=0.0132V
- induced emf=0
<h3>What is the emf induced in this coil when it is all inside the field.?</h3>
(A)
Generally, the equation for the flux is mathematically given as
So, the magnetic flux through the coil is constant.
From faradays law,
---(1) for the induced emf. Since magnetic flux is constant, LHS. of (1) =0
induced emf=0
(B)
Let x be the length of the coil's magnetic field area.
induced emf=0.0132V
(C)
In conclusion, Therefore, there is no variation in the magnetic flux across the coil when magnetic flux=0.
induced emf=0

Answer:
Part a)
Angle in degree is given as
Part b)
Size of the object is
Explanation:
Part a)
As we know that
180 degree = radian
so we have
so we have
Part b)
As we know that the relation of angle with radius is
