Answer:
Two stars (a and b) can have the same luminosity, but different surface area and temperature if the following condition is met:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
Explanation:
The luminosity of a star is the total energy that produces in one second. It depends on the size of the star and its surface temperature.
L = σ(T^4)(4πR^2)
L is the luminosity f the star, T is the temperature of the surface of the star and R is its radius.
Two stars can have the same luminosity if the relation between the radius and the surface temperature is maintained.
To see this lets suposed you have 2 stars, a and b, and the luminosities of each one of them:
L_a = σ(T_a^4)(4πR_a^2)
L_b = σ(T_b^4)(4πR_b^2)
you can assume that L_a and L_b are equal:
σ(T_a^4)(4πR_a^2) = σ(T_b^4)(4πR_b^2)
Now, you can cancel the constants:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
as long as this relation between a and b is true, then the luminosity can be the same.

The Gulf War was a conflict that involved Iraq, Kuwait, and 39 additional countries. The leader of Iraq, Saddam Hussein, invaded the small country of Kuwait and seized its oil fields. The president of the United States at the time, George H.W. Bush, led a coalition of 39 countries to stop Saddam Hussein and to help the citizens of Kuwait. The conflict in Afghanistan began in 2001 after the United States was attacked by a terrorist group. The United States believed that Afghanistan was harboring the terrorists responsible for the attacks, so it invaded the country and overthrew its government. The efforts to rebuild and stabilize the country are ongoing. The war in Iraq started in 2003. The conflict was between Iraq, the United States, and a few US allies. It was believed that Iraq was in possession of weapons of mass destruction and also linked to terrorist activities. The United States invaded Iraq and overthrew its government. The efforts to rebuild, stabilize, and create a democracy in Iraq are ongoing. Many internal conflicts, known as the Arab Spring, erupted in the Middle East starting in January of 2011. Citizens in countries such as Lebanon, Egypt, Syria, Tunisia, Libya, and Bahrain led protests against their governments. The people living in these countries are tired of living under dictators that do not allow them to participate in government and treat them unfairly.
