How Does This Energy Conservation System Work?

AI Thread Summary
The energy conservation system described involves a ball that, after being pushed, falls onto a turbine connected to a generator, producing electricity. The ball then travels down a tube, opens a valve, and returns to the water, where it is pushed again to repeat the cycle. However, this process does not create energy, as the ball loses kinetic energy when turning the turbine and requires work to open the valve. The discussion also touches on the physics of a stationary bike, noting that a rider falls when it is stationary due to lack of balance but remains upright when moving. Overall, the system illustrates the challenges of adhering to the principle of conservation of energy.

A system is developed as shown in the diagram attached. The ball is initially given a push so that it falls onto a turbine connected to generator which produces electricity. After rotating the turbine the ball fall down a narrow tube with a valve into the water again the ball rises again and is again given a slight push and the whole process is repeated again and again. In this way energy is being "created". The question is: How does this machine obeys the principle of conservation of energy?
Secondly, Why does a raider raiding a bike falls when the bike is stationary but does not fall when its moving? I know that this question has been asked before but I can't find it.
Any help will be appreciated.:smile:
(Pardon me for my bad english.)

Do you think it is possible to push the ball through the valve and into the water without doing any work?
 
No I dont. In my opinion the KE of the ball will be used to open the valve...
 
And, of course, the ball will have lost some of its energy in turning the turbine.
 

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}...
