AI Thread Summary
To determine the tension in a tightrope where a person balances in the middle, the problem involves a rope length of 14.2 meters and a sag of 2.3 meters. The person's weight is given as 630 N acting downward. To solve for the tension, it's suggested to draw a diagram and sum the forces acting on the person. The key equation to use is F=ma, where the forces include the weight of the person and the tension in the rope. Understanding these concepts is crucial for accurately calculating the tension in the rope.

Homework Statement



a person balances in the middle of a tightrope 14.2m in length. the middle of the rope is 2.3m below the secured ends. if the persos weight is 6.3x10^2 N(down) determine the magnitude of the tension in the rope.

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 'Struggle to understand the concept of the 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...
