Coulombs Law and Atomic Radius So, I understand that atomic radius gets smaller in groups as you go right, but I was wondering if this explanation is good when trying to use coulomb's law to explain it: The atomic radius gets smaller as you move right in a group because of the inverse relation of charge strength and distance with electric charges as stated in Coulomb's law. As you get higher in atomic number across a group, the effective nuclear charge is stronger on the valence electrons and as a result, they are pulled closer to the nucleus. I have a test upcoming and I was wanting to know if this is sufficient or if there is anything I can do to improve it, thanks!
Good Medieval/Fantasy Rpg games Hey, I really do enjoy the RPG genre when it has the medieval/fantasy theme. To give some background, Morrowind and Obllivion were two of my favorite games ever and I still enjoyed Skyrim too. I also enjoy runescape. I know that every game isn't going to be an ES game so what are some other suggestions? I was looking at Dragon's Dogma and that looked pretty good, but I'm open to other thoughts.
Physics Projectile Motion Help Hey, I'm having trouble with this one problem, "A stone is thrown outward from the top of a cliff that's 59.4 meters tall with an upward velocity of 19.5 meters per second. How long is the stone in the air?" I know the answer is 6 I just don't quite know how to get there.
