AI Thread Summary

A mass attached to a stretched spring experiences two main forces: gravitational force acting downward and the spring's restoring force acting upward. When the mass is motionless, it indicates that these forces are balanced, resulting in a net force of zero. The equilibrium state means that the upward force from the spring equals the downward gravitational force. Therefore, the net force on the mass is zero, confirming it is at rest. Understanding these forces is crucial in analyzing systems involving springs and masses.

1. A mass is attached to a stretched spring and hangs motionless. What forces act on the mass? What is the net force?

I think that the forces are gravity and the springs restoring forces, but I am not sure which way the net force is? What is the net force?

Well, if the mass is motionless, that means it's at rest. What does this tell you about the net force?

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 '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}...
