you have a bag of cotton and an iron bar, each indicating a mass of 100 kg when measured on a weighing machine. in reality, one is heavier than the other. can you say which one is heavier and why?

thank u

if our weight is 42 kg in a weighing machine , in reality is it more or less than 42 kg?

if a value is determined experimentally will that not mean that it depends on those terms which were responsible for its determination. does this mean that any constant is independent of any factor.

gravitation constant has been determined experimentally by cavendish. Its value has been found to be always a constant. The expression for G is given as G=Fd*d/Mm. I would like to know- on what factors does gravitation constant depend?
