 May 23 comment Please explain this circular movement problem Well, I realize that if the car was just standing there, he would act upon the hill with the force of 10kN. And it's pretty obvious to me that if it was going any faster, the hill would be "pushing him up", and once it would come to the top it would almost fly away. That's why the force is lower when it's moving. May 23 comment Please explain this circular movement problem You mean centripetal, right?

Apr 20 comment Is the Avogadro's constant equal to one? Whoops my bad again! Apr 19 comment Is the Avogadro's constant equal to one? Actually, that sums up to 1 mole = 6.002*10^23 mole, which, mathematically, obviously isn't correct. Apr 19 comment Is the Avogadro's constant equal to one? Hm, sorry then, I must have misread the formula! Also, I wasn't the one that -1'd you. Apr 19 comment Is the Avogadro's constant equal to one? Waaa, you're a professor at PMF? That's awesome! For me the choice is basically either PMF or FER... Apr 19 awarded Supporter Apr 19 awarded Commentator Apr 19 comment Is the Avogadro's constant equal to one? I seriously don't get you guys. Speed of light has a measurement unit of m/s, while dozen is just a number. Until you divide the equation with c, I don't see how could you use c = 1... And that doesn't really make sense. Apr 19 comment Is the Avogadro's constant equal to one? Oh wow. I don't get it. I thought humans had no idea what time is, and now you're telling me that we're transforming into distance... Damn. Can you please give me a link where I can educate myself about this? I don't want to wait 3 years just for my school to start teaching me relativity... Apr 19 comment Is the Avogadro's constant equal to one? Wait wait wait... Measure time in meters? Are you trolling me? If so, 10/10, would rage again. Apr 19 comment Is the Avogadro's constant equal to one? Nope, it isn't ;) Apr 19 comment Is the Avogadro's constant equal to one? @LubošMotl. 1 mole = 6.022 * 10^23. NA = 6.022 * 10^23 * mole^(-1). NA = 6.022 * 10^23 * (6.022 * 10^23)^(-1). This is literally one. Where c is actually not one, so I wouldn't say that they're isomorphic... Apr 19 awarded Student Apr 19 comment Is the Avogadro's constant equal to one? But mathematically, G and c aren't actually one, and I guess you have to scale all other things when you set them to 1, but what I'm saying that Na literally is one. Apr 19 awarded Editor
