Answer:

Absolute Magnitude (Luminosity) and Spectral class (Temperature)

Explanation:

Hertzsprung-Russell diagram, popularly known as HR Diagram, shows the relation between the absolute magnitude (or Luminosity) and temperature of stars (spectral class). HR diagram helps in understanding the stellar evolution. One can predict the life-cycle of a star with the help of this plot. One can see, with the help of HR Diagram, that stars spend 90% of their life time in main sequence stage where the fusion of Hydrogen takes place in the core.

Ejnar Hertzsprung and Henry Norris Russell created this plot in 1910.

<h3><u>Answer;</u></h3>

Mid-ocean ridges

<h3><u>Explanation</u>;</h3>

Sea-floor spreading is the process by which molten material adds new oceanic crust to the ocean floor.
Mid-ocean ridge is an undersea mountain chain where new ocean floor is produced at a divergent plate boundary.
Mid ocean ridge occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

Answer:

The velocity is $v = c* \sqrt{1 - \frac{1}{n^2} }$

Explanation:

From the question we are told that

a = nb

The length of the minor axis of the symbol of the Federation, a circle, seen by the observer at velocity v must be equal to the minor axis(b) of the Empire's symbol, (an ellipse)

Now this length seen by the observer can be mathematically represented as

$h = t \sqrt{1 - \frac{v^2}{c^2} }$

Here t is the actual length of the major axis of of the Empire's symbol, (an ellipse)

So t = a = nb

and b is the length of the minor axis of the symbol of the Federation, (a circle) when seen by an observer at velocity v which from the question must be the length of the minor axis of the of the Empire's symbol, (an ellipse)

i.e h = b

$b = nb [\sqrt{1 - \frac{v^2}{c^2} } ]$
