Answer:
volt ÷ ampere
Explanation:
The mathematical form of Ohms law is given by :
V = IR
Where V is voltage
I is current
R is resistance
The unit of voltage is volt and that of current is ampere
Unit of resistance :
So, volt ÷ ampere is the same as the unit of resistance. Hence, the correct option is (a).
Answer:
Explanation:
Given that,
Force exerted on an antique car, F = 270 N
Time, t = 0.275 s
Distance, d = 0.3 m
To find:
The angular momentum given to the engine.
Solution,
We know that the relation between the angular momentum and the torque is given by :
Since,
So, the angular momentum given to the engine is .
