Its resultant is 100 newton
√(60 square+80 square)
Yes! with out the sun plants and animals wouldnt live right? therefore they get energey wich is passed on by food
You've failed because you failing becomes a statement rather than it becoming fact or what actually happened.
Answer:
It is<em> impossible</em> to construct a machine which produces the <em>work output greater than the work input.</em>
Let us consider the II law of thermodynamics.
According to Kelvin Plank's statement any engine/machine does not give hundred percent efficiency. And violating the PMM-II(Perpetual motion of machine II kind), Always some amount of energy transferred to the sink or surroundings.
Therefore
W(ouput) = Q₁-Q₂
There are many reasons to lower the work output, just for an example friction between the mating parts reduces the work output.
