AI Thread Summary
Lightning occurs due to the induction of opposite charges between clouds and the ground. While the Earth does attract the cloud, this force is minimal and insufficient to pull the cloud down significantly. The phenomenon of hair standing on end before a lightning strike indicates the presence of a strong electric field. This electric field can create a potential difference that leads to lightning. Ultimately, the interaction between the cloud and the ground is complex, but the attraction does not result in the cloud being pulled to the ground.

Homework Statement



We were reading about lightning and how the cloud has a different charge than the ground. We know that lightning happens because of induction. But if the charges are different, why doesn't the Earth pull the cloud to the ground, or repel it higher into the air?

It wouldn't repel the cloud, since the charges are opposite; but it does attract the cloud, although it is a very small movement. More noticeable might be your hair standing up straight up on end just before the bolt strikes...if it does, you're in big trouble...crouch low, click those heels together, block your ears, ...and pray:wink: ...
 

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}...
