Spring Constant and Time Period

Click For Summary
Changing the spring constant affects the time period of Simple Harmonic Oscillations, and maintaining constant air humidity is crucial for controlling air resistance and damping. Absolute control over humidity is challenging, but suggestions include aiming for extremes of 0% or 100% humidity to simplify the experiment. Maintaining relative humidity consistently can be difficult, so creative solutions are necessary. The discussion emphasizes the importance of controlling variables for accurate experimental results. Effective humidity management can enhance the reliability of findings in physics experiments.

Hi,

I am investigating the effect of changing the spring constant on the time period of Simple Harmonic Oscillations.

My first doubt regards one of my control variables. I listed that I should try and maintain air humidity constant, due to the fact it affects air resistance and, therefore damping. Obviously, I don't have absolute control over the humidity in the air but how could I try to maintain it constant? Maintaining the relative humidity the same

Any ideas?

Thanks,
Peter G.

Not that you would actually do this in an introductory physics lab, but probably the easiest way to control the humidity is to keep it at or close to either 0% or 100%; maintaining it somewhere in between would be very tricky. See if you can think of ways that holding it at either 0 or 100% might be done.
 
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?
