Answer:
Explanation:
Let:
We need to know for which value of the function
is equal to
:
Therefore, we need to solve for the previous equation for :
Replacing the values of and
:
Subtract 4 from both sides:
Multiply both sides by -1
Divide both sides by 3:
Therefore the value of for which
is
.

Answer:
Explanation:
f = Frequency = 75 Hz
B = Magnetic field =
d = Diameter of cell =
t = Time taken
= Angular frequency
The expression of emf is
Emf is maximum when and N = number of turns = 1
The maximum emf that can be generated around the perimeter of a cell in this field is
