A green cloud with 2 concentric white lines surrounds the center, with 2 small green balls marked with minus signs on the inner white line and 2 small green balls marked with minus signs on the outer white line. How many neutrons does this atom have? 4 6 10 14

10

Explanation:

Amu denotes for unified atomic mass.

it is mostly used to define the atom's mass and molecules.

we know that

One unit of amu is 1 ÷ 12 of the mass of a nuclide 12C

And 1 u = 1.660 538 921 × 10-27 kg

In the inside we can found that there is 10 nucleons so here the alss of the atoms would be 10 amu  

truck y has a greater velocity than truck x.
