The discussion focuses on the task of consolidating nodes in a circuit to minimize their number. One participant points out that a critical connection between the parallel resistors R2 and R3 to resistor R6 was deleted, altering the circuit's integrity. They present a revised drawing of the circuit and seek validation for their changes. The importance of maintaining essential connections while simplifying the circuit is emphasized. Proper node consolidation is crucial for accurate circuit representation and analysis.

Homework Statement
Redraw the circuit consolidating nodes into the minimum number possible.
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 .
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...
