    Buoyancy Lab
AI Thread Summary
To create a buoyancy lab for extra credit, the main task is to demonstrate the buoyant force equation, F = pvg. The student is unsure how to proceed since they have not covered buoyancy in class. They plan to measure the weight of an object in air and then its weight when submerged in water to find the buoyant force. However, they seek clarification on how to accurately measure the weight underwater. Understanding these measurements is crucial for successfully completing the lab.

Homework Statement


Create a lab that proves the buoyant force equation; on a separate sheet of paper

That is the directions


Homework Equations


F = pvg

The Attempt at a Solution


We haven't done anything to do with buoyancy, this is extra credit. I'm not sure what to do.

So I got that I would have to get the weight above water, and then get the weight when it is submerged in water and the force would equal the weight difference. How do I get the weight underwater?
 

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...
