Could you post a photo of the graph?
The answer is simple Neptune because it is the only blue planet.
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.
Im pretty sure its the NCR ( Nuclear Regulatory Commission ) <span />
Ya, teknologi hijau membantu pembangunan masyarakat berilmu yang mendorong ke arah mempraktikkan tenaga lestari dan cara hidup lebih baik. Kita boleh hidup lebih lestari jika kita menjadi seorang yang lebih celik alam sekitar, belajar daripada alam semula jadi, hidup dengan lebih sederhana dan menjadi rakyat yang aktif dalam membangunkan alam sekitar.
