Answer:
False
Explanation:
Anything that sits and does nothing will keep doing nothing until an outside force moves it.
Atmospheric electricity and storms,electric current in a vacuum,spark discharge,electrostatic control filters and industrial electrostatic separation <- those are just a few
The separation between them is
Concept :
If the force increases, distance between charges must decrease. Force is indirectly proportional to the distance squared.
Given,
Two point charges are brought closer together, increasing the force between them by a factor of 20.
Original force is
F = -------- ( 1 )
Here, are charges and r is the distance between them
New force F' = ----------- (2 )
Divide ( 1 ) and ( 2 )
=
20 =
r' =
Given that force between them are increasing and therefore distance between them decrease by

Answer:
the boat would be deeped by 3200 m
Explanation:
Given that
The boat arrives back after 4 seconds
And, the speed of the sound in water is 1,600 m/s
We need to find out how much deep is the water
So,
As we know that
Distance = ( speed × time) ÷ 2
Here we divided by 2 because the boat arrives back
= (1600 × 4) ÷ 2
= 3200 m
Therefore the boat would be deeped by 3200 m
