Answer:
it is a measure of the heat content of fuels or energy sources
Explanation:
Answer:

Explanation:
First let's find the electric potential using y = 22.5:



Then, to find the magnitude of the electric field, we just need to divide the electric potential by the distance y:



Slope of I-V graph is Resistance.
Its S.I. unit is Ohm.
The symbol of ohm is Ω.
Frequency is 1/period. f=1/0.5 = 2Hz
I believe the answer is electric
