i need tips on how to get a mark on the physics exam coming up in 2 weeks. I have trouble connected concepts with problem-solving; for example i know archimedes principle for buoyant force but have trouble solving problems related to finding tension in a suspended mass in water. So any tips on how to do well would be great! Thanks o:)

Do lots and lots of practice problems. That is the best way to learn how concepts can be used to solve problems. It will also give you experience and familiarity with the types of problems that could come up on the test. Make sure you understand the physical meaning behind fundamental concepts and equations.
 
Thanks for ur reply
 
Good luck, by the way! :smile:

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}...
