    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 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
