AI Thread Summary
To identify the forces acting on an object, it is essential to draw a closed curve around the system, define "the system" and "the environment," and create a visual representation of the situation. All three tasks—A, B, and C—are valid steps in this process. The consensus in the discussion confirms that these steps are necessary for accurately identifying forces. The correct approach involves a comprehensive understanding of the system's context. Thus, A, B, and C are indeed the correct steps to follow.

Consider the following tasks:

A. Draw a closed curve around the system.
B. Identify “the system” and “the environment.”
C. Draw a picture of the situation.

Which of these are steps used to identify the forces acting on an object?

A only
B only
C only
A, B, and C
None of themI was thinking A, B, and C? Am i correct?

I felt pretty positive with A, B, and C, and it turned out to be correct.
 
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...
