Well, first of all, I don't think "After the collapse of a nebular cloud ..."
is the first time that "atoms begin gravitating together".  Seems to me like
that's what was going on all the time, and it's what caused the nebular cloud
to collapse in the first place.

In any case, once the pressure and temperature at the center get high enough,
you get "ignition" of nuclear fusion, and that's when you first have a "star".

Answer:

The core of the star is ignited.

Explanation:

Through the acummulation of mass caused by gravitation, the protostar becomes heavier and heavier until the pressure in its center, the core, is enough to initiate thermonuclear reactions. This reactions will be the source of the energy of the star during its entire life, as long as it shines.

The amount of mass needed for the protostar to ignite its core is known as stellar mass.

Gekata [30.6K]

Answer:

We obtain the average velocity instead of the instantaneus velocity.

Explanation:

The problem with calculating speed in this way is that an average speed is being calculated and not an instantaneous speed at a given point.

V_{average} =\frac{x}{t} \\where:\\x = distance\\t = interval of time

To calculate the instantaneous speed, a very small space interval must be measured at a given time.
