E, 63% of the value. I forget the rationale behind it but I learnt that in engineering. 90% confident for that answer.
To solve this problem it is necessary to use the concepts related to the Hall Effect and Drift velocity, that is, at the speed that an electron reaches due to a magnetic field.
The drift velocity is given by the equation:

Where
I = current
n = Number of free electrons
A = Cross-Section Area
q = charge of proton
Our values are given by,






The hall voltage is given by

Where
B= Magnetic field
n = number of free electrons
d = distance
e = charge of electron
Then using the formula and replacing,


Answer:
temperature
Explanation:
when you put a water on the stove the water will start to boil there for temperature
Answer:
It is because it is a unit of Power(which is a derived quantity)
