Hello all, I would like to know what is the theory behind the formula of the rms speed, Vrms = root(3rt/M). Thank you

I see. So if we have a tank of height H, and we fill it with water with height h and then we close it tightly so it won't have contact with the atmosphere and assuming that a point A exists in the bottom of this sealed tank. What will be the pressure (under normal conditions) at that point A...

Hello all, i would like to know if atmospheric pressure exists on the surface of water in a completely sealed water tank. So, does atmoshperic pressure exist even on surfaces that are not in contact with the atmosphere, meaning in closed areas above. Thank you.

Never mind, I solved it. (x/(x(1+1/x)))^x = (1/(1+1/x))^x = 1^x/(1+1/x)^x where 1^x = 1 and (1+(1/x))^x as x tends to inf = e^1 therefore as x tends to infinity the function tends to e^-1

Yes, i meant (x/(x+1))^x

Can someone help me with finding the limit of (x/x+1)^x as x tends to infinity

I'll give it a try. But why can't it be solved as we do x^k ? Like k*x'*x^(k-1)

Hello all. I would like to know what is the derivative of 2^x and how it is done. Thank you
