Answer:
The mass of electrons are so small that it is pretty much insignificant.
Explanation:
mass of proton = 1.673*10^-27
mass of neutron = 1.675*10^-27
mass of electron = 9.109*10^-31
the electron's mass is about 0.0005 times the mass of a neutron
Answer:
The correct answers are:
Qualitative; quantitative
Explanation:
According to Piaget's theory, the cognitive approach in children changes in a qualitative way since human beings develop their capacities in different ways as they grow and get mature, processing the acquired information in different ways as well. He says it happens in a qualitative manner, more than a process of accumulation of information where more and more information is stored.
On the other hand according to the information-processing approach which is mainly adopted by cognitive psychologists, the knowledge acquisition is mainly based on a quantitative model, in which information is processed according to the number of experiences and storage of information that will be used when necessary. This model is generally compared to that of a computer in which an amount of information can be stored to use later.
