It is noon at the Prime Meridian in Greenwich, England. What time is it 60 degrees east of the Prime Meridian?

4 pm

Explanation:

The lines of longitude also known as the meridian are imaginary lines that run from north to south and  measure the position east-west of a point. The lines of longitude are used to determine the time at a location. Below shows the relationship between the change in degrees and time.

1° = 4 minute, 15° = 1 hour

The prime meridian is at 0°. The degree change between the prime meridian and a point 60° east of the meridian = 60°

change in time = 60° * 1 hour / 15° = 4 hour

Time at 60° east of the meridian = Time at the meridian + change in time = 12 pm + 4 hour = 4 pm

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.
