Homework Statement
calculate the angular momentum vector L
Homework Equations
r = rr(hat) r=√(xsquared + y squared) r(hat) = <cosθ, sinθ>
v = r(dot)r(hat) + rθ(dot)θ
The Attempt at a Solution
L = mv X r
I don't know m, how can i calcuate L? please help me
hello guys
if the water surface is at same temp as air above, and humidity is 100%, do any wataer molecules leave their liquid state to become vapour ie evaporate?
I couldn't remember what professor said exactly, so i checked up on internet and it says
water can't evaporate at 100%...
