Im confused ok i have that the mass of a proton is 1.6726231 x 10^-27 and the mas of an electron is 9.1093897 x 10^-31 charge of an electron is 1.602 x 10^-19 what do i do with all of this, is g1 the charge of the proton g2 the charge of the electron? what is d is that 10 m?

Someone please help me, I am having the worst time understanding this problem. Where do I begin? Atomic physicists ignore the effect of gravity within an atom. To see why, calculate and compare the gravitational and electrical forces between an electron and a proton separated ...

Suppose you are studying coordination compounds of Co(II) with the ligand pyridine (py, C5H5N, MW = 79.10). You isolate a crystalline compound and since the only available ions are chloride and nitrate, you hypothesize the empirical formula of the coordinaton compound must be ...

SCIENCE - Pls HELP
A proton (with a mass, mp = 1.673 x 10^-27 kg & electrical charge, e = 1.602 x 10^-19) and an electron (with a mass, me = 9.109 x 10^-31 kg & electric charge -e = -1.602 x 10^-19) are not moving & at a distance of 1.000 x 10^-10 m apart.... (assuming the electrical constant, ...

Using the intersection method, I need to solve the following equation: 5x-3.3=x-2.1 Can you point me on the right path? you have to get x's on one side, and the numbers on the other. then solve for x. Kira, Thank so much for your help, but how do you graph the equation to ...

what is the answer to 5x-16=14-5x Just giving you the answer is not what this forum is about. We'd be defeating the purpose of you assignment by doing that. Try to work the variables to one side, say the lefthand side, and the numbers to the other side. Add 5x to both ...
