you already have the density and dont need to work it out
mass of the ball = 0.3kg
density of the ball = 100kgm^(-3)
re arrange your density formula to solve for volume, v
v=m/d
insert numbers and out pops the volume
v = 0.3/100 m^3
hi,
i am trying to show that the amount by which a vector is rotated by parallel transport around a triangle whose sides are arcs of great circles equals the excess of the sum of the angles over 180 degrees.
this is what i have found out so far
call the angles of the triangle (assuming...
thanks for the reply!
i'm not sure i completely understand. for starters i cant see how you can say that -p0> -p1 and p0>p1. doesnt mutliplying by a negative change the inequality. and in your tiny step guide i see it boils down to showing whether X<Y, which was the the part i wasnt sure...
hi
i am trying to show that for 2 probabilities p_{0} and p_{1} that X=\frac{p_{1}}{p_{0}} cannot be further from 1 than Y=\frac{p_{1}(1-p_{0})}{p_{0}(1-p_{1})}
how i went about the problem was as follows:
i split it into 3 cases, case 1 is where p_{0}=p_{1}, case 2 is where p_{0}>p_{1}...
