No. If it takes 15 minutes to get to work, then it takes him another 15 minutes to get home. That means he travels 30 minutes each day going to and from work.

I don't understand what you are asking for. Do you want the percent by mass of each element in the compound? Or by atom or mole? For example, NaCl is clearly 50% Na by ATOM. By mass, Na is 23.0 of the total molar mass of 58.5, or 39.3% Do the others the same way, if that is ...

Since all charged particles that I know also have mass, the answer is yes. However, the gravity force is much less than the Coulomb force for fundamental particles, and is usually ignored. The ratio of gravity to electrical force is about 10^-39 in an atom

hard to show long algebraic division on this forum, I hope you are familiar with synthetic division It will look something like this 3 | 3 4 -7 6 ........9 39 84 ... 3 13 32 102 so (3x^3+4x^2-7x+6) / (x-3) = (3x^2 + 13x + 32) + 102/(x-3)
