The smallest time interval in which the magnetic field can be turned on or off to induced the emf is 47.5 s.
<h3>
Emf induced in the coil</h3>
The emf induced in the coil is calculated as follows;
emf = dФ/dt
where;
- dФ is change in flux
- dt is change in time
0.12 = 5.7/dt
dt = 5.7/0.12
dt = 47.5 s
Thus, the smallest time interval in which the magnetic field can be turned on or off to induced the emf is 47.5 s.

Answer:
25
Explanation:
I looked at it and its 25
Power is defined as rate of work done which means it is work done in 1 second of time
Now it is given that we have a horse that will give power 745.7 W
So it will do work of 745.7 J in 1 second of time
now if we wish to find the work done by horse in 0.55 s
so we can say
So it will do total work of 410.14 J in 0.55 s of time
Not sure what the answer choices are.

Answer:
A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.
