Answer:
The opponent-process theory
Explanation:
The opponent process theory is based on the human visual system and according to the theory the interpretation of the color is done by the photo-receptors rods and cones in the human eye.
This theory states that the perception of color is governed by the two opponent system which includes - a red-green, a blue-yellow and a black-white mechanism.
Any activity in one of these restricts the activity in the other.

Let say the height of two balls from the ground is H
now we can use kinematics

now we have


now in the same time ball on the left will cover the horizontal distance between them
![v_x = \frac{d}{ t}[/tex[tex]v_x = \frac{3}{\sqrt{\frac{2H}{g}}}](https://tex.z-dn.net/?f=v_x%20%3D%20%5Cfrac%7Bd%7D%7B%20t%7D%5B%2Ftex%3C%2Fp%3E%3Cp%3E%5Btex%5Dv_x%20%3D%20%5Cfrac%7B3%7D%7B%5Csqrt%7B%5Cfrac%7B2H%7D%7Bg%7D%7D%7D)
<em>so above is the horizontal speed of the left ball</em>
Answer:
Option A
Beryllium fluoride
Explanation:
The combination of Beryllium (Be) and Fluorine (F) leads to formation of a compound called Beryllium fluoride (BeF). The name is changed to fluoride and not fluorine because the salts of fluorine are called fluoride salts. Beryllium has oxidation state of +2 being a metal with atomic number 4. Fluorine is the lightest halogen and known to be the most electronegative element due to its high affinity to attract electrons and it has atomic number 9. The combination of Be and F is a salt.
Answer:
Ground State.
Explanation:
Term used for electrons in an atom at their lowest possible energies is called Ground state. Also, it electrons are said to be in excited state when they gain some energy and jump to higher states. the electrons in excited state is always more than in their ground state.
