The distance to a lightning bolt can be determined by counting the seconds between the flash and the sound of thunder due to the speed of light is greater than the speed of sound
We must consider that the speed of light (3.00× 10⁸ m/s) is greater than the speed of sound (340 m/s), this is why we can first see the lightning and after seeing it we can hear it.
In order to calculate the distance we must count the time since the lightning bolt and use the speed of sound, applying the following formula:
x = v * t
Where:
- x = distance
- t = time
- v = velocity
It is a physical quantity that indicates the displacement of a mobile per unit of time, it is expressed in units of distance per time, for example (miles/h, km/h).

The electrostatic force between two charged objects is given by
where
k is the Coulomb's constant
q1 is the charge of the first object
q2 is the charge of the second object
r is the separation between the two objects
In our problem:
So if we plug these numbers into the equation, we can find the electrostatic force between the two objects:
