AI Thread Summary
The discussion revolves around expressing vector R in terms of vectors A, B, C, and D. Two potential equations are proposed: R = B - D and R = A + C. The initial attempts to solve the problem highlight confusion regarding the relationships between the vectors based on their directional arrows. Participants confirm that while both equations are valid, neither is definitively the stated answer to the problem. The conversation emphasizes the need for clarity in vector relationships to arrive at the correct expression for R.

Homework Statement


Express the vector R in terms of A, B, C, D
(VIEW IMAGE ATTACHED)

Homework Equations

The Attempt at a Solution


R=B-D
OR
R=A+C

In this problem, I figured that because of the way the arrows are pointing R+D=B which you can then simplify to R=B-D. However, this is not an answer to the problem.

I then tried using the other triangle with R. Because of the way the arrows are pointing, I figured that A+C=R. However, this is also not a solution to the problem.

Right. And one of those works just fine.
 

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}...
