Which shows the correct order of processes leading up to the formation of a main sequence star? a. gases condense to form a nebula, gravity causes the nebula to collapse and spin, nuclear fusion occurs, and a protostar forms. b. a protostar forms, nuclear fusion occurs, gases condense to form a nebula, and gravity causes the nebula to collapse and spin. c. gases condense to form a nebula, gravity causes the nebula to collapse and spin, a protostar forms, and nuclear fusion occurs. d. a protostar forms, gases condense to form a nebula, gravity causes the nebula to collapse and spin, and nuclear fusion occurs.

Option c

Explanation:

Nebula is a birthplace or stellar nursery where stars take birth. Gases condense to form a nebula. Then these gases start to collapse under their own gravity. This heats up the matter which is condensing which gives rise to a protostar. After the formation of protostar, if the mass is sufficient and temperature is high enough, nuclear fusion reaction kicks in at the core and starts to release energy and enters the main sequence.

Hence, the correct order of process leading up to the formation of main sequence star is: option c

answer: i think he can see forward ten seconds and move forward ten seconds but giorno can undo his actions with ger.

explanation:

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
