- Derivative of the Volume of a Cone - Physics Forums
You will have, now, a related rate for the volume of a cone This is correct to the best of my knowledge, and I note the fact that I took the derivative of the radius, r, because it, too, is not constant (as you can obviously imagine, as it changes depending on how high or low you go in the cone)
- How is dθ dt related to v r in circular motion? - Physics Forums
ω=dθ dt now θ is the angle of an arc of a circle of radius r and arc length l so θ=l r So ω=d dt(l r) r doesn't change so
- Why doesnt blood dry inside our bodies? - Physics Forums
Legit question When we get a cut or scrap, blood comes out In a few moments the blood dries and forms what looks like a layer of dried blood that gets a darker color If that happens, why doesn't blood dry inside our bodies?
