Answer:
Thus, the induced current in the coil at  is 9.98 A.
 is 9.98 A.
Explanation:
Faraday's law says 

where  is the number of turns and
 is the number of turns and  is the magnetic flux through the square coil:
 is the magnetic flux through the square coil: 
Now, 



 ;
; 
therefore, 



is the emf induced in the coil. 
Now, the loop is connected to  resistance; therefore, at
 resistance; therefore, at 





Thus, the current in the coil at  is 9.98 A.
 is 9.98 A.
 
        
             
        
        
        
Answer: A = y/cos32
That is the amplitude A in terms of the displacement y.
Explanation: Since the displacement in the question In the question is the same in both direction, it is a Simple Harmonic Motion problem. In s.h.m the amplitude of displacement A is related to the displacement itself y by this simple equation
y = A* cos(theta)
So, A = y/cos(theta)
A = y/cos32.
If the magnitude of the displacement y is given, you just substitute in.
 
        
             
        
        
        
<h3>Question:</h3>
How to find g (acceleration due to gravity)
<h3>Solution:</h3>
We know,
Acceleration due to gravity (g)

where, G = Gravitational constant 

M = Mass of the earth

R = Radius of the earth

Putting these values of G, M and R in the above formula, we get

So, the value of acceleration due to gravity is

Answer:
1. Primary or P waves are push and pull waves
2. Secondary, S or Shear Waves are also called transverse wave
3. L or surface waves reach the earth's surface after P and S waves
