Answer:
Explanation:
Check the attachment for the ray diagram
Ray diagrams are important in locating the position of image of an object. It enables us to determine the nature of image formed by an object in from of a mirror or lens.
When drawing ray diagrams to locate the image I of an object O, there are two important steps to follows:
1. Ray emitted from the tip of an object O incidented on the mirror and parallel to the principal axis OP pass towards the focus F of the mirror after reflection.
2. The ray emitting from the tip of the mirror and passing through the centre of curvature of the mirror C undeflected reflects back on the same line of incidence. (Principle of reversibility).
Not sure if this is what you’re looking for. Let me know if I can clarify anything.

Phosphorus needs 3 electrons to complete its outter most shell of electrons
Big Bang is a theory that, as stated above, has grown to become widely acceptable scientific explanation of the origin of things. Research would say that according to this theory, the Earth originated billion years ago through an explosive of a highly energized point.
Through this explosion, the elements were formed. However, only the lightest of the elements including hydrogen and helium, with traces of lithium and beryllium. From the choices, the answer would have to be the second choice, helium.
Answer: B. helium
