Cultural landscapes can be parks, cemetery, tombs, anything shaped by human involvement
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:
The poor people
Explanation:
The poor people always the ones that suffer the most when there are negative changes. They are not financially capable to avoid the problems that come upon them, and plus they are overly dependent on the nature for their survival. These people can not afford or do not have healthcare that is eligible, so if there is a pandemic they will be the first ones affected, and by far the most affected. They depend mostly on agriculture for their survival, and it is agriculture in more primitive manner, which is the one that suffers the most from the climate changes and the natural disasters. If the crops fail dramatically only one year, it will have huge effects, if that happens several years in a row, it can be one of the biggest, if not the biggest humanitarian crises in the world.
