Answer:
Divide by 3
Explanation:
In order to estimate the distance traveled by a lightening flash in kilometers, we follow these simple steps:
- Make a count of the number of seconds in between the period a flash occur and the thunder accompanied by the lightening flash is heard.
- Dive the total number of seconds by 3 to get the distance traveled by the flash. This is because in order to cover 1 km, it roughly takes 3 seconds.

Sound
Answer:
The change in momentum is 
Explanation:
From the question we are told that
The time taken for the stone to stop is 
The net force on the rock is 
The impulse of the rock can be mathematically represented as
Substituting values
Now impulse is defined as the rate at which momentum change
Hence the change in momentum 
of the rock is equal to the impulse of the rock
So

➷ A normal atom has the same amount of electrons and protons, making it neutral. An atom develops a positive charge when it loses an electron(s). Once it loses an electron(s), there would now be more protons that electrons.
Short answer: by losing an electron(s)
