Air Volume Water

AI Thread Summary

The discussion centers on calculating the volume of an iron anchor that weighs 200N less in water than in air. The buoyant force is used to determine the volume, with the formula relating buoyant force to density and gravity. Participants are encouraged to share their calculations and any specific questions they have regarding the problem. The weight of the anchor in air is also a point of interest, as it relates to the volume derived from the buoyant force. Engaging in problem-solving and sharing attempts is emphasized for better understanding.

An iron anchor of density 7870 kg/m cubed appears 200N lighter in water than in the air.
a) what is volume of anchor?
b) what is its weight in the air?

I set volume equal to buoyant force/ density x gravity

Thread 'Errors and significant figures'

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
