Answer:
i = 0.5 A
Explanation:
As we know that magnetic flux is given as

here we know that
N = number of turns
B = magnetic field
A = area of the loop
now we know that rate of change in magnetic flux will induce EMF in the coil
so we have

now plug in all values to find induced EMF


now by ohm's law we have


Answer:

Explanation:
= Permittivity of free space = 
A = Area
h = Altitude = 600 m
Electric flux through the top would be
(negative as the electric field is going into the volume)
At the bottom

Total flux through the volume

Electric flux is given by

Charge per volume is given by

The volume charge density is 
Answer:
the speed is equal to 6 m/s
