Answer:
C) A ratio based on the mass of a carbon-12 atom
Explanation:
For each element, there is a characteristic number of protons, this number represent a type of atom and its called the atomic number
On the other hand we have the number of neutrons, and for one element which difers only on the number of neutrons, we have different isotopes from one element.
Together, protons and neutrons define the mass number
One property linked with the mass number, is the atomic mass, which is formerly expressed as "uma" (atomic mass unit)
By definition, one atom of carbon-12 (with 6 neutrons) has an atomic mass of 12 umas
The air pushes the engine with an equal force in the opposite direction.
Whenever force is used there is an opposite yet equal affect.

it is a living thing and not modeling anything
You haven't given us enough information to figure out an answer.
It depends on whether the light bulb is part of a series or parallel circuit,
and whether there are also OTHER light bulbs in the same circuit.
-- If the light bulb is the ONLY one in the circuit, or if it's one of
several bulbs that are connected in parallel across the same battery,
and you replace it with a bulb that has higher resistance, then the
new one will be LESS BRIGHT than the original one.
-- If the light bulb is one of two or more bulbs connected in series
across the battery, and you replace it with a bulb that has higher
resistance, then the new one will be BRIGHTER than the original
one was.
