Acoastline is a narrow sea between two close landmasses .

FALSE

Explanation:

A coastline is usually defined as a long extending land that occurs along the edges of the oceans and seas. These are formed due to the deposition of the sediments from the rivers that join the seas and also due to the deposition of the sediments from the seas. The coastlines are generally considered to be the meeting point of land areas and the seas.

But, a strait or a channel is described as a narrow type of channel that runs between any two close landmasses.

Thus, the above statement is False.

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
