Answer:
5500000 millimeters
Explanation:
 1 kilometre= 1000 meter
 5.5 km=5.5 * 1000
 =5500
Now,
 1 metre = 1000 millimetres
 5500 metre=1000*5500
 =5500000 mm
 
        
             
        
        
        
Answer:
67.44 V
Explanation:
Number of turns N =123
Radius = 2.41 cm =0.0241 m
The magnetic field strength increases from 50.9 T to 96.3 T so change in magnetic field dB = 96.3-50.9=45.4 T
Time interval dt = 0.151 sec
We know that the induced emf
