Profit is producer surplus, minus fixed costs. In other words, its price minus variable costs. Profit, however, is price minus total cost. Since fixed cost is never negative, profit will always be less.
The atom is about 10-10 meters (or 10-8 centimeters) in size. This means a row of 108 (or 100,000,000) atoms would stretch a centimeter, about the size of your fingernail. Atoms of different elements are different sizes, but 10-10 m can be thought of as a rough value for any atom.
Protons have an effective size of about 1.2 x 10-15 m, and the nucleus is râ¦oughly the cube root of the number of nucleons (protons and neutrons) times that typical proton size, usually still on the order of 10-15 to 10-14 m in size. The charge on an electron is -1.
