Determine what forces are present in this situation : an elevator is rising at a constant speed; the elevator is the object in this situation .
a) gravity and tension
b) normal and tension
c)normal, gravity, tension
d)gravity

The correct answer for the given question would be option A. The forces that are present in the given situation above which is an elevator rising at a constant speed, are gravity and tension. Gravity is the force that pulls all matter together. Tension is the pulling force transmitted axially. Hope this is the answer that you are looking for.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
