AI Thread Summary
The discussion focuses on a student's solution regarding tensions in a mass-weight system, which lacks clarity in notation and definitions of forces. Reviewers express confusion over the repeated notation "FT=FT=FT" and suggest that it does not effectively convey the calculations. They note that the calculation for the 5kg mass indicates no vertical acceleration, which is assumed to be correct without proof. Additionally, the calculations for the 1kg and 2kg masses are acknowledged as acceptable, but the use of distinct symbols for different tensions is recommended. Overall, the feedback emphasizes the need for clearer notation and definitions to enhance understanding.

I don't understand your notation. Can you please define what the various forces represent. And what does FT=FT=FT mean?
 
Your "For 5kg" calculation appears to be showing that the mass on the table has no vertical acceleration. I think we can assume that without proof.
Your "For 1kg" and "For 2kg" calculations are ok except that you should use different symbols for the two different tensions.
As Chet notes, "FT=FT=FT" is not very illuminating, and I can make no sense of the calculation which follows.
 

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...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
