For any force and any mass, the acceleration is always
(the strength of the force) divided by (the mass) .
If a force of 5 newtons is applied to a mass of 5 kg, the acceleration will be
(5 Newtons) / (5 kg) = <em>1 m/s²</em>
Explanation:
It is given that,
Let Charge of
is taken from points A & B such that
.
We need to find the energy of charge. Electric potential is defined as the work done per unit of electric charge. So,

So, the energy of charge decreases by
. Hence, the correct option is (a).
Pretty sure it's C) condensation because all of the others required heat to be added
Answer:
56250 N
Explanation:
mass, m = 6000 kg
initial speed, u = 20 m/s
final speed, v = 5 m/s
distance, s = 20 m
Use third equation of motion

5 x 5 = 20 x 20 + 2 a x 20
25 = 400 + 40 a
a = - 9.375 m/s^2
Braking force, F = mass x acceleration
F = 6000 x 9.375
F = 56250 N
