AI Thread Summary
The problem involves calculating the volume and density of an object that weighs 313 N in air and 254 N in alcohol with a density of 0.7 g/cm3. The volume was determined to be 8.6 L by calculating the difference in weight and converting to kilograms. However, confusion arose regarding how to calculate the object's density using the known values. Clarification is needed on which force represents the total weight of the object and how to correctly apply the density formula. The discussion emphasizes the importance of showing all steps in the solution process for better understanding.

Homework Statement


A particular object weighs 313 N in air and 254 N when immersed in alcohol of density 0.7 g/cm3. What are the volume and the density of the object?

Homework Equations


D=m/vL

The Attempt at a Solution


I found the volume by: 313-254 N to find the actual weight, then I divided it by 9.8 to get it into Kg, then I used the density formula to solve for volume which gave me 8.6L

So the volume is taken care of! 50% of the problem done :)!

As for the density, I'm confused because I thought I would just plug in my known values but it doesn't work. Can someone please guide me as to how I would find the density of this object? I greatly appreciate it!

Can you show what you do and get when you say "just plug in my values".

6.02kg from the two forces/ 8.6L that I found out from part a) =D

but it doesn't :[
 
Which force represents the total weight of the object? What you are solving for above is the density of the alcohol.
 
Can you please solve the second part pleaseee, need it for an assignment thanks

Usual forum rules... please post your attempt first.
 

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...
