Answer:
The use of interchangeable parts (parts that are exactly alike) helped factories produce more goods at cheaper prices.
Explanation:
In the process of development of industrialization, the qualifications of workers and employees were gradually increasing. There was a need for a scientific approach for the accelerated development of industries. As a result, at the beginning of the 20th century, a related concept of industrialization appeared - Fordism. This term includes 4 components:
Separation of personnel: manager, engineers, and technicians performing low-skilled work.
The introduction of standardization in the engineering industry with the goal of interchangeability of parts and assemblies suitable for different products.
The optimal organization of workshop production, giving maximum returns.
Establishment of a conveyor at the final stage of product formation.
The answer to your question is: last option.
20 protons
20 electrons
25 neutrons
Explanation:
Data
Calcium, atomic number 20
Atomic number indicates the number of protons in an element, so, if Calcium's atomic number is 20, it means that it has 20 protons.
In a neutral element, the number of protons = number of electrons, then
Calcium has 20 electrons.
Only the number of neutrons could change.
According to the previous description, the last option is correct. ( also put the options too)
