How has scientific experimentation affected the model of an atom? a. the atomic model has become more accurate because of this experimentation. b. the atomic model has become a less accurate representation of the actual atom. c. we understand less about the atom due to these experiments. d. we are less able to design an accurate model as a result of these experiments.

Option (a) is the correct answer.

Explanation:

Before experimentation we were not aware of the sub-atomic particles present in an atom. But after the experimentation, we came to know that an atom consists of protons, neutrons and electrons.

After that we came to know that protons and neutrons reside inside the nucleus and electrons revolve around the nucleus of the atom.

Hence, we can conclude that scientific experimentation affected the model of an atom such that the atomic model has become more accurate because of this experimentation.

i think it is d. e because the next one is igneous.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
