Answer:
Induced emf, 
Explanation:
The varying magnetic field with time t is given by according to equation as :

Where
are constant
Let
is the emf induced in the loop as a function of time. We know that the rate of change of magnetic flux is equal to the induced emf as:





So, the induced emf in the loop as a function of time is
. Hence, this is the required solution.
Option D is correct. The speed at which the earth's surface moves because of the earth's rotation will then be equivalent to -10³ km/hr
Speed is a body is defined as the ratio of the distance with respect to the time taken by the body. Mathematically:
Speed = Distance/Time
GIven the following
Distance = 104km/hr
If it is 6:00 p.m. in New York, it is 7:00 a.m. of the next day of the week in Tokyo, this means that the time difference between New York and Tokyo is 11 hours.
Time = -11 hours
Get the required speed
Speed = 104/-11
Speed = -9.454545
Speed = -10km/hr
The speed at which the earth's surface moves because of the earth's rotation will then be equivalent to -10³ km/hr
