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:
B) Singapore and Hong Kong
Explanation:
In Euromoneymagazine's 2017 semi-annual "Country Risk Rating. Singapore and Hong Kong was found to be the countries with the lowest political risk. This was as a result of stability in government which reduces the risk that their government would default on its financial commitments. And no possible changes in the business environment that may negatively affect operating profits.
A. Plea bargain
Explanation:
Plea bargain is one of the common strategy used to reduce the court's caseload and reduce cost of trials.
This process involves an agreement between the prosecution and defendant where the defendant agrees to plead guilty in order to receive some pardon or reduced sentence.
Plea bargain helps fast-track the legislative process helps to reduce cost on prolonged trails.

Answer: migrantes estão no caminho e não se sabe do estatus deles {exilados, fugitivos etc etc} e nem sempre sabemos o objetivo, ponto final ou destino deles. Imigrantes são pessoas que acabaram de chegar no país que lhes recebeu (expressao "imigrantes" descreve a perspectiva dos habitantes do pais que lhes recebeu). Emigrantes sao aqueles que abandonam o país (expressao "emigrantes" descreve a perspectiva do habitantes do país de origem).
Explanation: As três palavras tem significado diferente e sempre requerem compreensao. Migrante está no caminho, imigrantes está chegando ou já chegou, emigrante está abandonando o pais de origem.
