Answer:
It represents the amount of speed per time or (x) for speed (y) for time so the slope would be like y/x
Answer:
the exposed core of a dead star, supported by electron degeneracy pressure.
Explanation:
A white dwarf is a low luminosity exposed core of a dead star having mass comparable to the sun but volume comparable to the earth . So its density is very high . These stars have lost the capacity to generate energy through the process of fusion . Due to high gravitational energy , it goes on shrinking but ultimately balanced by electron degeneracy pressure. It is not a main sequence star as it has lost the power of fusion .
Using the formula
GPE = m*g*h (mass (kg) * gravitational field strength (N/kg) * height (m) )
We can say that -
100 J = 0.5 * 9.8 * x
x = 100/(0.5 * 9.8)
<u>x = 20.4 m</u>
Your answer is 20.4 m
he meant that it was different from most galaxies as it is a "late stage major merger: two recently combined massive galaxies"
