Because it is also the thinnest of material
Since density would be D=M/V, we’d have to literally divide 20 by 4.
20 divided by 4 is 5, so the density of the mineral sample is 5 grams.
Please correct me if I am wrong!
MAX PLANCK <span>was responsible for the contribution that light is emitted and absorbed in bundles that are dependent on the frequency of a light wave.
In 1900, Max Planck proposed that </span>proposed that light<span> and other </span>electromagnetic waves<span> were emitted in discrete packets of </span>energy. These packets are called "quanta". <span> This discovery became the stepping stone of the quantum theory.
This discovery was used by Albert Einstein as basis for his realization that light was made up of photons. Thus, giving credence to "photoelectric effect".

True. If something is thermal, that means that by getting to close to it, you could get burned.
