Answer:
B, A, A, B
Explanation:
Just trust me on this one.
if in 1 second the jet goes 428 meters and you want to know how long it takes to go 237 meters you just divide 237/428
it can be written like this
_1_ = __x__
428 237
cross multiply
428 times x = 1 times 237
428x=237
divide by 428 on both sides
x= 237/428
x=0.5537 seconds
Answer:
So magnetic field will be equal to 0.1144 T
Explanation:
We have given frequency f = 60 Hz
Maximum emf e = 5500 volt
Number of turns N = 150
Area 
Emf generated in ac generator is given 
For maximum emf 
So maximum emf will be equal to 

So magnetic field will be equal to 0.1144 T
