Thomas discovered cathode rays when he was working with electrons. He was performing experiments with electrons when one of them became electrically charged and a beam of light came from it, this creating a cathode ray.
The the mass of the heavier isotope of chlorine (in amu) is 73.932 amu.
<h3>What are isotopes?</h3>
The term isotopes refers atoms that have the same atomic number but different mass number. We must know that all these atoms belong to the same element an differ only in the number of neutrons present in the atom of the element. Hence isotopes are different atoms of the same element hence they have the same chemical properties or reactivity. The mass spectrum is able to show the masses of each of the isotopes according to their order of relative abundance in nature.
Looking at the peaks, we know that the heaviest isotope is the one whose mass will have the highest peak as shown in the mass spectrum of the element as shown. Thus, the the mass of the heavier isotope of chlorine (in amu) is 73.932 amu. The mass spectrum of element also shows this fact.

Answer:
A. Fault blocks
Explanation:
The block mountains are formed by pieces of the crust that breaks down and pieces are pushed up by the movement of the crust around them. These type of mountains usually have a steep and a slope side, due to the irregular nature of the fracture. Example of such mountains are the Sierra Nevada mountains in North-America.
<u>They're not caused by the collision of two tectonic plates</u>, like most of the mountains of our planet.
Answer:
Silver fluoride because it is the most soluble compared to the others.
Explanation:
I believe it would be the sum of protons & neutrons which equals 9 amu....
