Find the net force on a rope which is being pulled by 2 groups of students. The blue team is pulling with a force of 1500 N to the west and
the orange team is pulling with a force of 1300 N to the east.

200 N to the west b/c we have 1500 to west and

1300 N to east . the forces have a opposite direction.

thus we add the force. and we gain 200N force.

there all right good

explanation:

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
