Find the slope (s) of the graph and state one precaution taken to ensure accurate results if you are to perform the experiment in the laboratory. d. Calculate the volume of the cone given that the base radius is 10.5cm and the height of the cone is 15.5cm. (Take π=3.142)

Faraday's Law of Induction states that the magnitude of the induced electromotive force (EMF) in a circuit is directly proportional to the rate of change of magnetic flux through the circuit. Mathematically, it is expressed as:

• $\mathcal{E}$: This is the induced electromotive force (EMF), measured in volts (V). It represents the voltage generated in the circuit due to the changing magnetic flux.
• $N$: This is the number of turns in the coil. It is a dimensionless quantity.
• $\Phi_B$: This is the magnetic flux through the circuit, measured in webers (Wb). It is a measure of the total magnetic field passing through a given area.
• $t$: This is time, measured in seconds (s).
• $\frac{d\Phi_B}{dt}$: This represents the rate of change of magnetic flux with respect to time, measured in webers per second (Wb/s).
• The negative sign: This indicates the direction of the induced EMF, as described by Lenz's Law. It means that the induced EMF opposes the change in magnetic flux that produced it.
