Answer:
- fragmenting states
- artificial landmasses
Explanation:
There are several ways a new state could form even if all of Earth's land was allocated to current nations. One of the possibilities is that a current state fragments to form two (or more) smaller states.
Another possibility is that nations construct artificial landmasses or habitable platforms in the oceans that are independent countries. Finally, in the future it may be possible to settle the continent of Antarctic if the Antarctic Treaty is ever not renewed.

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.
Most people work in the tertiary sector.
<span>Most people work in the tertiary sector is false because in developing economies most people work in the primary sector or in the secondary sector. the tertiary sector is about services, which are connected to a form of economy that is already developed. In this case, it is rare that people from developing countries work in the tertiary sector.</span>
