AI Thread Summary

To calculate the time it takes for an alpha particle to move halfway through a magnetic field circle, one must apply the centripetal force equation (Fc = mv^2) and the force equation (Ft = mv). The discussion highlights the need for additional information, such as the particle's speed, to determine the distance traveled. Participants emphasize the importance of a complete problem statement and a clear attempt at a solution for effective guidance. Clarification of the question is essential for accurate calculations. Understanding these principles is crucial for solving problems related to motion in magnetic fields.

...Huh? Can we get the complete question here and a genuine attempt at solution and specific question?

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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}...

Thread 'Understanding Forces and their Vector Components'

I was told forces are vectors so they can be divided into x and y components, but what about the normal force or the force of static friction? do you divide those into x and y components if say you had a block that was lying on an angled surface?
