Homework Statement
These questions are regarding water undergoing SHM in a u-tube.
Q1) What is the effect on the time period and damping in a u-tube when using oil instead of water?
Q2) What is the effect on the time period if the liquid (inside the u tube) is heated?
Q3) How can the internal diameter of the u-tube affect successive amplitudes of oscillations? Devise a suitable experiment.
Homework Equations
N/A
The Attempt at a Solution
Q1) T is unchanged; oil is more viscous so friction between inside of tube is greater thus oscillations die away quickly.
Q2) Heating water makes it expand; length of water increases; T increases.
Q3) I think the ratio between successive amplitudes should be the same... could plotting T against D (diamter) and observing the relationship be sufficient?
Are these right? Can someone please expand on them?
Many thanks.
