His answer was incorrect because according to ohm's law the formula used should have been R=V/I instead of multiplying and the answer should be 8ohms
Answer:
Option b
Explanation:
Metamorphism is the process where the variation of the geological texture resulting from the different arrangement of the minerals or the variation of minerals in protoliths, i.e., pre- existing rocks take place such that there occurs no change in state of the protolith, i.e., it does not melt into magma.
The change takes place as a result of the presence of chemically active fluids, heat and pressure.
There is a reaction between the chemically active fluid and the rock through which it passes and promotes the movement of the dissolved ions of silicate and promotes the growth of the mineral grains.
Answer:

Explanation:
Apply Faraday's Newmann Lenz law to determine the induced emf in the loop:

where:
variation of the magnetic flux
is the variation of time
#The magnetic flux through the coil is expressed as:

Where:
N- number of circular loops
A-is the Area of each loop(
)
B-is the magnetic strength of the field.
- is the angle between the direction of the magnetic field and the normal to the area of the coil.

=0.0250T/s is given as rate at which the magnetic field increases.
#Substitute in the emf equation:

Hence, the induced emf is
