    Energy Tension
AI Thread Summary
The discussion revolves around a friction-free pulley system lifting a 600-N block. Participants seek clarification on the number of rope strands supporting the weight, the tension in each strand, and how the man's pulling affects the block's movement. Questions also arise about calculating the ideal mechanical advantage and the potential energy increase based on the work done. The need for a diagram is emphasized to aid understanding of the system's mechanics. Overall, the conversation highlights the complexities of force and energy transfer in pulley systems.

1. A 600-N block is lifted by the friction-free pulley system shown.

a. How many strands of rope support the 600-N weight?

b. What is the tension in each strand?

c. What is the tension in the end help by the man?

d. If the man pulls his end down 60 cm, how many cm will the weight rise?

e. What is the ideal mechanical advantage of the pulley system?

f. If the man exerts 60 Joules of work, what will be the increase of PE of the 600-N weight?

okay so for A is it just 1 because its just 1 rope.
and B do we do F*D?
c. the same thing?
idk I am really confused.
please help!

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}...
