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.
Answer:
this is useful because they represent the shortest distance between two points on a sphere.
Explanation:
Due to the earth's rotation, sailors and pilots using great circle routes must constantly adjust their route as the heading changes over long distances.

Answer:
The decision of "racial segregation in public school" did Brown versus Board of education 1954 overturn.
Explanation:
The well known supreme court case in 1954 of Brown versus Board of Education of Topeka in which the justices had taken control unanimously over the racial segregation of children in the public school are completely unconstitutional. The brown versus Board of Education is the biggest milestone of the civil rights movement, which has helped to establish the precedents that are being "separate-but-equal" education rights and other services are not equal at all.
