Each stream in a drainage system drains into a certain area. In a drainage basin the water falling in the basin drain will fall into the same stream. A drainage divides drawing basin from other drainage basins
Answer: 
Explanation:
According to <u>Coulomb's Law:</u>
<em>"The electrostatic force 
between two point charges 
and 
is proportional to the product of the charges and inversely proportional to the square of the distance 
that separates them, and has the direction of the line that joins them".</em>
<em />
Mathematically this law is written as:
Where:
is the electrostatic force
is the Coulomb's constant
and 
are the electric charges
is the separation distance between the charges
Solving:
Bromine has 7 electrons in their valence shell.......
