Click For Summary
The accepted range for experimental values varies by experiment and can sometimes be subjective. To determine if values fall within this range, one can use the formula involving the absolute difference between accepted and experimental values divided by the accepted value. Discrepancies may arise from equipment limitations or skill levels, prompting a need for evaluation of results. It is essential to assess whether improvements can be made to enhance accuracy. Ultimately, understanding the accepted range is crucial for evaluating experimental outcomes effectively.

What is the "accepted range"?

Homework Statement



Were your values within an acceptable range? If not, find reasons for the discrepancy.

Homework Equations



( |Accepted value - experimental value| ) / accepted value

Absolute value of accepted value-experimental value over accepted value

The Attempt at a Solution



I'm not sure, I just don't know what the accepted range is.

The accepted range is different for each experiment. At times it is subjective. You are probably being asked for a subjective evaluation of your accuracy. Could you improve your results in some way. Was your result the best that could be expected given your equipment and skill?
 


Okay, thanks.
 
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?
