Answer:
It is a solution
Explanation:
I know that because a solution is something you mix and you have to use a microscope if you really wanna see what's in there
To measure a vector is to characterize both its direction (in one form or another) and a value (usually, a number). For example, velocity of a car moving on the road is a vector and, to measure it, we have to specify its direction (e.g. North or at angle 20 degrees from the North) and value (e.g. 40 m/sec).
Mixture. Mixtures can be separated into their component parts, while substances are chemically bonded atoms that can't be separated by physical means.
I believe body waves can actually reach the core as they follow raypaths refracted by the varying density and modulus of Earths interior.
Hope this helps!
