The equation 3z/2 = z/6 + 4 is analyzed for correctness. Initial calculations led to z = 1/2, but this was incorrect due to a miscalculation involving the constant. Correctly multiplying both sides by 6 yields 9z = z + 24, simplifying to 8z = 24, resulting in z = 3. The discussion emphasizes the importance of properly handling constants in equations. The final conclusion is that the correct solution is z = 3.
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...
