What is the density of the bird statue?

AI Thread Summary
The discussion revolves around calculating the density of an antique bird statuette using measurements from a spring scale. The statuette weighs 11.81 N in air and 11.19 N when submerged in water, allowing for the determination of its volume through the difference in weight. The density can then be calculated using the formula ρ = m/v, where the mass is derived from the weight readings. The conversation also explores whether the statuette is made of gold or gold-plated aluminum based on its density. The thread encourages participants to share their attempts and challenges for better assistance.

Homework Statement



An antique yellow statuette of a bird is suspended from a spring scale. The scale reads 11.81 N when the statuette is suspended in air, and it reads 11.19 N when the statuette is completely submerged in water.
a. Find the volume of the statuette
b. Is the bird made of gold? (ρ=19.3 x 103 k/m3g)
or gold-plated aluminum? (ρ=2.7 x 103 k/m3g)

Homework Equations


ρ(density)=m/v (mass/volume)
FT+Fb=Fg
Fg=mg

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'

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...
