Answer:
The answer is "Choice C ".
Explanation:
The relationship between the E and V can be defined as follows:
Let,
When E=0
v is a constant value
Therefore, In the electric potential in a region is a constant value then the electric-field must be into zero that is everywhere in the given region, that's why in this question the "choice c" is correct.
Answer:
The efficiency of this engine is 37.63 %.
Explanation:
Given;
useful output work done by the combustion engine, = 356 kJ
input work, = 946 kJ
The efficiency of the combustion engine is calculated as;
Therefore, the efficiency of this engine is 37.63 %.
