Answer:
False
Explanation:
Hierarchical diffusion is the spread of information from one hierarchical level to another, usually downwards, but can also be upwards.
An example of downwards propagation is when the president of a company announced there will be cuts in various departments. He transmits the news to the department chiefs, who relay it to the employees.
An upwards propagation might be when call center employees report repeated problems encountered by the customers to their supervisor, who moves it up to their boss and so on.
Gender and geography has nothing to do with that.
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. Earth's plates never move
Answer:
Montana
Explanation:
Montana is naturally a small state which means it will have the smallest airport.
