Which of these is not related to safety concerns? a. choosing a design that will fail in a safe way b. choosing a material that will show warning before it fails c. choosing a cheap material d. choosing a material that will fail in a predictable way

C.) Choosing a cheap material

The rest explain the reasons on why they could be/are unsafe

Good luck, and please mark brainiest:)

Option (C) is the correct answer.

Explanation:

A safety concern is a concern in which precautions are taken while conducting an experiment or risky work.

A cheap material is a material that will not last long and it is most likely prone to break easily.

So, when we choose a design that will fail in a safe way then it means we have followed a safety concern.

Therefore, we can conclude that out of the given options choosing a cheap material is not related to safety concerns.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
