Considering your previous knowledge of the science behind the concepts of supply and demand; please explain how the concepts are interconnected and how one affects the other to achieve market equilibrium.

The concepts of supply and demand go hand in hand in the field of business. A product which is more popular will be more in demand and hence, it productivity and supply will be more. Its supply might decrease if the owners are unable to meet the market demands,

On the other hand, a product which is not in demand will be supplied initially but its production will become less and so will the supply.

To achieve an equilibrium state, the demand and the supply of the particular product shall be the same i.e the amount of product being sold shall be equal to the amount of product being produced.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.
