Why Do Coupled Pendulums Exhibit Damped Oscillations?

AI Thread Summary
Coupled pendulums exhibit damped oscillations due to energy dissipation over time, which is a characteristic of damped oscillators rather than coupled oscillators themselves. The discussion highlights that while coupled systems can oscillate, the presence of damping is essential for energy loss. The diagrams referenced likely depict physical pendulums, which inherently experience damping and mechanical energy loss. Understanding this distinction is crucial in analyzing the behavior of coupled pendulums. Thus, the damped oscillations observed are primarily a result of the inherent damping properties of the pendulums rather than the coupling itself.

Dissipation of energy is not a property of coupled oscillators. This is a property of damped oscillators. The diagrams are probably taken from physical pendulums, which are necessarily damped and thus lose mechanical energy.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
