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.
They have mass, it is just too little in comparison to the mass of the neutron and protons to be taken into account. Therefore when measuring the mass of an atom, the mass of â¦ the electron are not used. (To be exact,9.10938188 Ã 10-31 kilograms, and the mass of proton is 1.67262158 Ã 10-27 kilograms.) Sidharth.D.
