Application of archimede's principle

AI Thread Summary
When an iron block floating in water is removed and then submerged, the displacement of water changes. Initially, the block displaces water equal to its weight while floating. Once submerged, it displaces water equal to its volume. The key question is which scenario results in greater water displacement, as this determines whether the water level rises, falls, or remains the same. Understanding Archimedes' principle is essential to solve this problem accurately.

Homework Statement


a jar containing an iron block was floating on water in a bigger container. the block was taken out and put into water. as a result, the level of water in the container will
(a)rise
(b)fall
(c)remains the same
(d)rise or fall depending on the mass of block

The Attempt at a Solution



the first case is the case of floating body. then weight of fluid displaced will be equal to the weight of the floating body. but in the second case body is immersed in fluid. so should there we consider apparent weight?

What you need to figure out is which situation displaces more water?
 
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 '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...
