Answer: The more massive an object, the faster it will accelerate.
Explanation:
<u>Answer:</u>
For a. Neutrons and electrons also form an atom.
For b. The element is oxygen which is a non-metal and will form a negative ion while forming ionic bond.
<u>Explanation:</u>
There are 3 subatomic particles which form an atom. These are neutrons, protons and electrons.
Neutrons carry no charge, protons carry positive charge and electrons carry negative charge. Neutrons and protons are present in nucleus and electrons revolve around the nucleus.
The energy which is present between neutrons and protons are nuclear energy and the energy which is present between electrons and protons are electrostatic energy.
In an element, number of protons is always equal to the number of electrons. The atomic number is equal to the number of protons or electrons. The element which has atomic number 8 is Oxygen.
The electronic configuration of this element is
This element requires only 2 electrons to form a stable electronic configuration. An element which gains electron is considered as a non-metal and forms a negative ion because number of electrons increases.
Answer:
B
Explanation:
Speed is the magnitude of the velocity vector, so it can never be negative.
The question is incomplete, the complete question is;
A scientist would most likely need to update her model when it
a.has become too simple.
b.no longer supports the latest results.
c.reduces the need for verbal explanation of data.
d.no longer appears interesting.
Answer:
b.no longer supports the latest results.
Explanation:
In science, models are prepared to explain experimental results. Each model must have a solid framework supported by experimental results.
However, science is never static. Given the dynamic nature of science, it is possible that latest experimental evidence may no longer support the existing model and the model will need to be reviewed in the light of emerging experimental results.
