    How much is molecules and how much is else in 1cm3 od air?

    Homework Statement I will try to translate the best I can: In 1cm3 of air, how much of it is molecules and how much is the space between them. diameter of 1 molecule is 0,1nm and is has a sphere shape. so R=0,1nm space=1cm3 Homework Equations V=4/3*R3*∏ n=N/Na=V/V0 Na=6,022*1023mol-1...

    How to transform acceleration from m/s2 to km/h2 and reversed?

    I would really need an answer within 20 minutes :D I guess if you have for ex. 5 m/s2 in km/h2 you would do 5*(1/1000)/(1/3600)2 if that is correct, how to finish? Do you really have to square 3600 or is there an easier way?

    How to transform acceleration from m/s2 to km/h2 and reversed?

    Homework Statement 0,27m/s2=? km/h2 Homework Equations 1m = 1/1000 km 1s = 1/3600 hours The Attempt at a Solution I have no idea.
