To solve this problem, use the ratio given by the total number of electrons or protons that exist as a function of the total charge, and inversely proportional to the value of the fundamental charge. The number of fundamental unit 
that constitutes a charge of 40.0C can be calculated as
Here,
= Value of charge and it is the fundamental charge
Q = Total Charge
N = Total number of electron or protons
The number of fundamental units is calculated as follows
Therefore the number of fundamental charge units moved by lightning bolt is 
Answer:
The carriage has the energy, W = 2469.6 J
Explanation:
Given data,
The height of the hill, h = 21 m
The carriage with the baby weighs, m = 12 kg
The energy possessed by the body due to its position is the potential energy,
<em>W = P.E = mgh joules</em>
Substituting the values,
W = 12 x 9.8 x 21
= 2469.6 J
Hence, the carriage has the energy, W = 2469.6 J
Is there a graph we can look at?
