The graph of the plot of acceleration against force is a straight line graph. Option B
<h3>What is the relationship between force and acceleration?</h3>
From the Newton's second law of motion we can derive that; F = ma
F= mass
a = acceleration.
This implies that the acceleration and the mass of a body has a linear relationship. We could then assert that the force is directly proportional to the acceleration with the mass being the constant in the equation.
As such, the force that is imparted to the body is what determines the acceleration and the both increases or decreases linearly. Thus the graph of the plot of acceleration against force is a straight line graph. Option B

Oxygen is participating in non-polar covalent bond(s)
Oxygen forms 2 covalent bond.
This is because oxygen atoms have 6 valence electrons. This means that it has 2 lone pairs and 2 unpaired electrons that are shared in order to achieve octet configuration.
In this chemistry, the 2 lone pairs on the oxygen are not shared with any other atoms. Instead; they are assigned to the oxygen atom. The formal charge on the oxygen atom is zero. Oxygen's atomic number is 8 and is equal to the sum of the number of its valence and inner shell electrons.
<h3>What is non-polar covalent bonding?</h3>
Nonpolar covalent bonding is a kind of covalent bond in which the bonding electrons are shared equally between the two atoms.

Answer:
The answer is "true"
Explanation:
ANP, or ANF, is a human peptide hormone, that controls your blood pressure, a cardiac atrium secretion hormone. It response primarily to the volume and stress expansion of the auricles and ventricles.
- ANP's main function decreases the amount of increased extracellular fluid by increasing renal excretion.
- This hormone is primarily developed by cardiovascular myocytes and, emanates from the wall tension locally, that's why the given statement is true.
I believe it is the third choice from the left because it is 3D and has the "sticks", unlike the space-filling model to the left of it. Hope this helped!
A) Certain electrons in the dye molecule move to a higher energy level, with the difference in energy between the lower and higher energy levels being the same as the energy of the absorbed photons.
Explanation:
The reason behind the photonsWhen UV photon or a photon of visible light is absorbed by an atom then the summation whole of energy of that particular photon gets all excited to a higher energy level. The following movement of an electron to a higher energy level from a lower energy level is called as a transition. A successful transition occurs only in that condition when the energy of the photons which gets absorbed should be greater than or equal to the difference in energy between the underlying energy levels. also,we know that once the electron is being excited to a higher energy level, it becomes more unstable for a fact we know that electron becomes stable only when iot ios grounded or in groud state. As such, the electron will quickly fall back down to the lower energy level and hence it emits a photon with an energy equal to the difference in energy levels.
