AI Thread Summary
The discussion revolves around calculating the voltage produced by a power station using water from a creek. Given that 10 liters of water fall from a height of 100 meters, the potential energy is converted into electrical energy, resulting in a direct current of 10 A. The efficiency of the electricity production is assumed to be 100%, leading to the conclusion that the voltage is 1000 V. Participants seek clarification on how to calculate Joules and the potential energy associated with the height differential. Understanding potential energy is crucial for solving the problem accurately.

Homework Statement



A Little power Station uses the water of a Creek. Per second 10 Liters of water fall from a height of 100 meters on the turbine of a power Station. A direct current I = 10 A ist produced. Find the voltage if the Efficiency of the electricity production is 100 %.

Homework Equations



The solution is: 1000 V


The Attempt at a Solution



10 l / s = 10 kg / s

v = J / C

C = 10 C/s

J = ?

How can I calculate the Joule?

Thanks in advance!

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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...
