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:
Columbus was a horrible man that killed, enslaved, tortured and raped Natice Americans when they did nothing to him besides welcomed him onto their land with open arms. He forced his believes onto Native Americans and brought deadly diseases that killed the majority of the Native population. A day that is "celebrated" because he "found" America (although he didn't) despite the awful things he did would be upsetting knowing that person is the reason millions had died.
Lattitude is going side to side and longitude is up and down so on a map you would put your finger on the longitude number and your other finger on the lattitude number and follow the lines connected to the number until the lines touch each other, where the lines touch each other is where you should plot your point.
