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:
Boreal forest
Explanation:
The boreal forest is a biome that is found in the Northern Hemisphere. It is located between the temperate forests and the tundra. These forests are dominated by coniferous trees. The climate is continental, with the winters being very cold and snowy, while the summers are pleasant with mild temperatures. The animals that live in these forests are the elk, moose, deer, wolverines, wolves, black bears, mink, foxes, lynx, among others. All these animals have special adaptations that enable them to live in this biome. They all have thick fur for most of the year, only shedding slightly during the summer.Their paws tend to winder and have goo isolation so that they can walk easily on the snow and avoid frostbite. It is not a biome that has very big diversity in flora and fauna, but it is not a one that lacks in it as well.
Answer: Their population will rapidly decrease in till eventually they are no longer.
Explanation: Due to having less and less area to nest, the costal bird species population will slowly start to decline.
Answer:
Its economy runs on recycling and reusing waste. With the amount of money they earn from each industry, it goes to show how much companies could benefit from sustainable waste management systems. ... With 15,000 factories dedicated to recycling and sorting Mumbai's waste, Dharavi employs 250,000 people just for this.
