Answer:
The atomic mass unit is 1/12 of an atom of carbon 12, and is a very small amount to represent in kilograms:
is atomic mass unit.
This is why the benefits of the atomic mass unit is that it makes the representation of atomic masses easier in terms of the simplicity of the numbers that are used to represent the masses. Also using the atomic mass unit it is easier to compare the masses of different atoms, These numbers would be very small and would require negative powers of 10 to represent them, so it is more convenient to use the atomic mass unit.
Answer:
A
Explanation:
The wavelength is the spatial time of an occasional wave, the distance over which the wave's shape rehashes.

A barometer measures the atmospheric pressure.
The value of the atmospheric pressure depends on many things, but mainly on the altitude. In fact, the value of the atmospheric pressure at a given location depends on the weight of the column of air above the location. As we go higher in altitude, the weight of this column of air decreases, and so the atmospheric pressure decreases.
Therefore, at the top of a mountain the barometer will read a value for the atmospheric pressure lower than the value measured at sea level.
