What is the effect of hand position on rotational motion?

AI Thread Summary
The discussion explores the effect of hand position on rotational motion, specifically in relation to angular momentum. Participants question the physical meaning of angular momentum and its perceptibility. A practical experiment is suggested, involving a rotating chair to demonstrate how hand positioning affects rotational speed and stability. The experiment compares two scenarios: hands on knees versus hands spread out. Overall, the conversation emphasizes the relationship between hand position and the dynamics of rotational motion.

What do you mean by perceptible?

You can make a simple experiment of Newton's 2nd law for rotational motion if you sit on a chair which can rotate, let someone spin you, and do this a) with your hands on your knees; b) with your hands spread.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
