Answer:
2 number
Explanation:
Displacement is a vector. This means it has a direction as well as a magnitude and is represented visually as an arrow that points from the initial position to the final position.
 
        
             
        
        
        
The reason for that is that P-waves (primary waves) travel faster than S-waves (secondary waves).
If we call 

 the speed of the primary waves and 

 the speed of the secondary waves, and we call 

 the distance of the seismogram from the epicenter, we can write the time the two waves take to reach the seismogram as


So the lag time between the arrival of the P-waves and of the S-waves is

We see that this lag time is proportional to the distance S, therefore the larger the distance, the greater the lag time.
 
        
        
        
Answer:
0.85V
Explanation:
The emf is calculated by using the Lenz's Law

But for this case we have that the magnetic field is constant. Hence we have

where we have taken that the intial time is t1=0
