    Integrals Shock wave
AI Thread Summary
Key equations in shock wave analysis often require a deep understanding of fluid dynamics and intuitive grasp of the concepts involved. Participants express confusion about the behavior of shock wave tails and seek clarity on fundamental principles. The discussion highlights the importance of foundational knowledge before tackling complex topics, as many find the material challenging. Concerns are raised about the effectiveness of instructional videos in conveying these concepts. A solid grasp of the basics is essential for progressing in shock wave analysis.

Homework Statement
I don't understand anything they do after 1:26 constructing the first diagram ("the zooming in part") and devising the integral.
Relevant Equations
provided here from 1:26 ONWARDS: https://www.youtube.com/watch?v=er512TwsxNM&t=86s
the attempted is the above ex. i needa justify why and figure out the reason behind those relevant equations.

Are you puzzled at the way the left and right tails become horizontal?

puzzled at everything. may someone start from scratch
 
If most of the video is puzzling, maybe is not the right point for you to start?

well most of it requires intuition, no?
 
I've only looked at the zooming in part so far, and might not get further today, but it does not give me great confidence in the tutor.
 

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}...
