Answer 1

Answer:

Q1 : Rudolf Clausius

Q2 : Michael Faraday

Answer 2

Answer:

Q1 ----Rudolf Clausius

Q2 --- Michael Faraday

Q3---- Gravitational pull

Q4---- If the output gear of a gear train rotates more slowly than the input gear, then the gear train is called a speed reducer (Force multiplier). In this case, because the output gear must have more teeth than the input gear, the speed reducer will amplify the input torque.
