For a star that has the same apparent brightness as Alpha Centauri A ( 2.7×10−8watt/m2 is mathematically given as
L=2.7*10^30w
<h3> What is its luminosity?</h3>
Generally, the equation for the luminosity is mathematically given as
L=4*\pi^2*b
Therefore
L=4*\pi^2*b
L=4* \pi *(2.83*10^{18})*2.7*10^{-8}
L=2.7*10^30
In conclusion, the luminosity
L=2.7*10^30w

Answer:
6
Explanation:
because I did this assignment, :) your welcome
Next time do it by yourself, but here's the answer kid
The core difference is that heat deals with thermal energy, whereas temperature is more concerned with molecular kinetic energy. Heat is the transfer of thermal energy, whereas temperature is a property the object exhibits.
Answer:

Explanation:
Let's define the variables to proceed with the operations,
So,
The masses



Average distances


Gravitational constant

The formula of the Gravitational Force between the Moon and the Earth would be,



This force is in the direction of the earth.
We perform the same process but now between the Sun and the Moon, like this,



This force is in the direction of the Sun
The net force must be


This in the direction of the Sun.
