comment Time for water wave to reflect
Sorry if i phrased the question wrong. I meant to ask will the bounce be instantaneous? What factors (even small ones) might make it non-instantaneous?

comment Is there a curve for which a particle restricted to move within it under the gravitational force will always exhibit a pure harmonic motion?
Sorry - a cycloid not a catenary. Here is the relevant wikipedia page

If memory serves me right the catenary has this property. I'll will try to find a source or a derevation

comment Distinguishing between solid spheres and hollow spheres (equal mass)
I wouldn't call this the "best" method but it made me smile: if the hollow one is filled with gas you can cool them down and hear the condensed gad sloshing around

comment Power dissipation in High Voltage Cables
But we can also express it $P=V^2/R$ also making it quadratic in voltage! In the end the current also depends on the voltage.

comment The physics behind Balloons lifting objects?
Shouldn't $F_{net}=m*g$ were $m$ is the mass of the object we want to lift?

Can Poiseuille's Law be used in cases where the pressure is a function of time?
