AI Thread Summary
The Earth's rotation does not significantly affect the fall of an apple dropped from a tree; the apple moves with the Earth as it falls. When the apple is released, it retains the horizontal motion of the Earth's surface, resulting in it landing close to the point of release. This principle is similar to how a thrown ball returns to nearly the same spot from which it was thrown. The apple's descent is primarily influenced by gravity, not the Earth's rotation. Overall, the apple's motion is consistent with the inertia of objects on the rotating Earth.

The Attempt at a Solution



Er... I'm not 100% sure on this one =/. Does it pull on it as it falls down or something? Help would be MUCH, much appreciated, thank you!

How does the apple move relative to the earth? I mean when the Earth spins does the apple move with the Earth or does it stay put while the Earth revolves?
 
I'm not sure, that was just one of the conceptual problems on the worksheet we got for reviewing the last few chapters (since finals are coming up) =/
 
Well turns out that the apple isn't effected in the normal sense. The apple moves with the earth. I mean if you throw a ball up it comes back down in almost the exact spot you threw it into the air, the same applies to the apple.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
