Answer:
A. Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.
Explanation:
Mass is also a scalar quantity associated with the amount of atoms and/or molecules that constitutes the object. While weight is a force due to the action of gravity (either on our planet or any other one) and therefore a vector quantity that we routinely use as scalar due to the fact that it is always pointing down (towards the center of the Earth) so we ignore a bit the direction associated with it.
Within a single medium, the product of (wavelength) x (frequency)
is always the same number, for all waves. (It's the wave-speed.)
This means that longer wavelengths must have lower frequencies,
and shorter wavelengths must have higher frequencies, in order for
the product to always come out to be the same.
