Transformation of energy, because energy cannot be created or destroyed
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.

A line of best fit is a straight line drawn through the most points on a scatter plot, with an equal number of points above and below the line. It is used to investigate the nature of the relationship between two variables. The correct option is d.
<h3>What is line of best fit?</h3>
A straight line with the best fit is one that minimizes the distance between it and some data.
In a scatter plot of varying data points, the line of best fit is used to express a relationship. It is a result of regression analysis and can be used to forecast indicators and price movements.
It is important to note that your line does not need to pass through any of the points on the plot; it only needs to bisect the area that contains the data points.
Thus, none of the options are correct, the correct one is d.
