What is the uncertainty in 5.00mm measured by analog device?

Click For Summary
The uncertainty in a measurement of 5.00mm using an analog device is typically calculated as half of the smallest division on the scale. Participants discuss how to determine the smallest division, which is crucial for calculating uncertainty. There is confusion about maintaining the correct number of significant figures in the final result. The conversation emphasizes the importance of understanding both uncertainty and significant figures in measurement. Accurate reporting of uncertainty is essential for precise scientific communication.

The Attempt at a Solution


I know that the uncertainty is half the smallest division but i can't figure out what is the uncertainty and how to keep the same number of significant figures!

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
