AI Thread Summary
To find the angle x between vectors A and B, use the equation x = arc cos(-10/AB), where AB represents the magnitude of the product of the vectors. The vectors can be translated to touch or intersect, which helps in determining the plane they lie in. The relationship between the vectors and their product indicates that they are in a specific geometric configuration. Understanding the intersection of the vectors is crucial for identifying the plane they define. This approach effectively combines vector mathematics with geometric principles.

If you were given vector A times vector B equals -10 and vector A times vector B = ABcos(x), how do you find x? also what plane is vector A and vector B on?

x = arc cos(-10/AB)
Translate vectors so that they touch each other, or intersect and they determin the plane they are in
 
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}...
