Thank you very much sir for helping me.

I thought about solving it using components of IAB but since it is a scalar quantity it doesn't seems to be correct . I don't think Perpendicular Axis theorem will work as required Inertia is in the same plane.

I see that time period of all the pulses will be same so all the pulses will have same frequency(up-down vibrations) so it is about vertical vibrations and not horizontal with which I confused .

So vibration is in vertical direction (up-down) , I thought it was in horizontal axis (left-right).

I agree that all the pulses will take same time to reach the top but how it relates to constant frequency?

I still can't understand how your example leads to the explanation that frequency is constant all over the rope. The elements in the upper part might vibrate less that the elements at the lower part leading to decrease in the frequency. Thank you very much sir.

You can write what ever you know about shape of drops,I will like to learn it as well.

I am Interested in determining the system on which the forces are acting and how the forces influence the contact angle of the drop.(I.e why liquid forms a specific contact angle due to resultants of all forces acting on it?)

I am trying to understand how fluids form particular shapes when put on a solid. In the two figures,what are we taking as a system for the forces? How the resultant of the forces influences the shape of the different fluids?

I have one final question , which part is exactly being considered in the drop as the system and how the resultant of the three forces acting on the system affect the shape of the drop?

RIP.

So what is the reason for the solid- liquid and solid-gas surface tension being horizontal and being opposite to each other?

I am a high school student and currently studying Mechanical properties of fluid. We are taught surface tension in a very introductory level and most of it is about liquid-gas surface tension. We are taught that liquid-vapour tension is the atrractive forces that water molecules experience at...
