Hi! Can you solve this problem ? I did not solve the problem. The course name is Heat Transfer. Thank you!
pls help me answer this question it is too hard for me
Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the fulcrum how long was the seesaw on Joe's side?

Can i get help with this physics(Energy conversion) questions 4.1 and 4.2 and for some figures see the pictures included down here 4. One of the most important energy conversion systems in our modern society is the electric power plant. It is shown schematically below. The chemical energy is first converted to thermal energy in the boiler; thermal energy is then converted to mechanical energy in the turbine; finally, mechanical energy is converted to electricity in the generator. System efficiency is, therefore, Questions 4.1 By how much does the efficiency of a turbine have to increase in order to raise the efficiency of a power plant from 35 to 40%. The efficiencies of the boiler and generator are 90% and 95%. 4.2 In order to achieve the efficiency increase in Problem 4.1 by how much does the inlet steam temperature have to increase? Assume that the efficiency is proportional to the temperature difference between hot and cold steam and that the cold steam is in both cases at 100 °C
