Balloon Physics: Impact of Punctured Balloon on Horizontal Balance

AI Thread Summary
When one of the two identical, pressurized balloons is punctured, the balance of the stick is upset due to the loss of weight from the popped balloon. The remaining balloon continues to exert downward force, causing the stick to sag towards the side of the intact balloon. This change occurs because the punctured balloon no longer contributes to the overall weight on that side. The discussion confirms that the physics behind this scenario is straightforward, with the balance being directly affected by the change in weight. Ultimately, the balance is disrupted simply by the removal of the downward force from the popped balloon.

Homework Statement


Two identical balloons are of the same volume are pumped up with air to more than atmospheric pressure and suspended on the two ends of a stick so the stick is horizontally balanced. If one of the balloons is punctured is the balance of the stick upset?

Homework Equations





The Attempt at a Solution


I say yes. But I don't know why.

If the contents of the two balloons have more than atmospheric pressure then the balloons are heavier than air. So?
 
So, if the balloon on the left is popped then the stick will sag towards the right, or the direction of the balloon that is left. Is it that simple? I thought there might be something I was missing?

Yes, both balloons are pulling down on the stick. If you pop one, it will stop pulling down. Simple as that.
 
Thanks.
 

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}...
