Answer:
You can use the mass-luminosity relation to find the star's lifetime in terms of just its initial mass. The lifetime = mass/luminosity × 1010 years is simply = (star's mass)/[(star's mass)p] × 1010 years = 1/(star's mass)p-1 × 1010 years. Remember that the star's mass is in solar masses.

Planet A is an outer planet, and Planet B is an inner planet, then Planet A will spin (rotate on its axis) faster than Planet B.
Using our Solar System as a model, we may determine the following:
The inner planets, which include our Earth, Mercury, Venus, and Mars, revolve more slowly than the outer planets (such as Jupiter, Saturn, Uranus and Neptune). The reason for this is because the nearest planets are held firmly in place as they revolve around the Sun due to the massive gravitational field of the star.
However, for the same reason (because of their proximity to the Sun's gravitational field), inner planets complete one circle around the Sun faster than outer planets.
As a result, Planet A will spin (rotation on its axis) faster than Planet B if Planet A is an outer planet and Planet B is an inner planet.

Answer: In terms of oil reserves, the Middle East is second to none. This “oil miracle” of the world has been shaped by a set of favorable factors, some global and others local, inscribed in the geologic history of the region.
