The microwave has 60% efficiency, this means that the power delivered (P=900 W) is 60% of the original power of the source, while the other 40% is dissipated.
We can write it this way:
where
is the power of the source, which we can find by re-arranging the equation:
There are times where the mass is less than the force of gravity or the gravitational pull. The gravitational pull will overpower the mass of the object, which is why you only notice the force of gravity and not the mass
A observation is gathering data.
A inference is a conclusion claimed on the basis of proof and reasoning.
Hope this helps :)
