The fact with more pulleys has to pull longer is conservation of energy or work

Mr. Michel, I believe you have errored in the video; I may not be able to present the whole solution here but I may write all the equations: I regard both hanging masses to be Fg1 and its tension to be Ft1, while the between mass to be Fg2 and its respective tensions to be Ft2 =} Ft1= Ft2 cos @ =} Fg1= Ft1 =} Fg2= 2 Ft2 sin @ =} Fg1 = Lim Fg2/2 tan @ @--> 0°

Thank you professor for this it helped me a lot, really sad that you didn't continue this serious I hoped that you would explain the IDEAL TRANSFORMER with coupling and maybe solve some find the impedance questions next , but unfortunately i dont know why you didn't continue the series

Hello Sir, Hope you and your family are doing great, two questions. 1. Why you didn't integrate using hook's law as in W = kxdx and instead you used W = 1/2kx^2dx? 2. Do you check your patreon, do you use it?

What is precession of equinoxes?
@MichelvanBiezen12 сағат бұрын
we usually express that in terms of the "Earth's precession" which has an effect on when the equinoxes occur. The data would shift over time, but that is counteracted by shifting the calendar periodically.

Professor, what is the the kinetic and potential energy per unit mass i(what is the the minimum and maximum value of potential and kinetic energy per unit mass ) in the troposphere and stratosphere? thank you professor
@MichelvanBiezenКүн бұрын
since the atmosphere is made up of gases we tend to consider the thermal energy per mol. U = nCv T where n = # of mols Cv = molar heat capacity at constant volume T = temperature in Kelvin
