Answer:
The unit of force is Newton.
Explanation:
Given that,
S.I unit of force = kg -m/s²
Time = second
We need to calculate the unit of force
A constant force exerted on the object, an interval of time during
The force is applied and the resulting momentum of the object P.
Using formula of momentum
....(I)
From equation of motion,
v = a t
From newton's second law

Put the value v and a in the equation (I)



Put the unit of the force and time

Here, 

Hence, The unit of force is Newton.
Answer:
Explanation:
Electrical energy is:
E = IVt
E = 210 * 12 * 10\\\\\\E = 25200 J
