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.
I believe the answer is C due to the fact that delta is built from rocks, mud, soil and moraines is built from rocks, sand, gravel and soil (I tried)
<span>The equator is 0 degree latitude. This imaginary line, which runs through parts of South America, Africa, and Asia, is officially the halfway point between the North Pole and the South Pole.</span>
<span>The prime meridian is 0 degrees longitude. This imaginary line runs through the United Kingdom, France, Spain, western Africa, and Antarctica.</span>
By using the equator and prime meridian, we can divide the world into four hemispheres, north, south, east, and west. For instance, the United States is in the Western Hemisphere (because it is west of the prime meridian) and also in the Northern Hemisphere (because it is north of the equator).
<span>These lines are merely for the identification of where things are on a map or a globe.</span>
To be frank, I don't think your question is specific enough, but I would say that the answer would be the Rocky mountains, or just mountains. those are the only major kinds of landforms I can think of
1.51 is the partial pressure of gas Y. as At 300 K, the volume of the flask that contains a gaseous mixture of two gases, X and Y, is 20 L. If the total pressure of the container is 2 atm and 0.1.
<h3>What is
gaseous mixture?</h3>
The gaseous combinations that are properly considered in this book are blends of different ingredients that may or may not vary outside of certain bounds.
These gases often belong to the category of "fuel gases," and each gas is any of a number of fuels that are gaseous at normal temperatures and pressure.
Thus, 1.51 is the correct answer.
