hi here is your answer hope it helps or then sry
Explanation:
The Great Artesian Basin (GAB) is one of Australia's most significant hydrogeological entities. Covering more than 1.7 million square kilometres, the GAB underlies parts of Queensland, New South Wales, South Australia and the Northern Territory.
Answer:
Mantaro River
Explanation:
The source of the Amazon River has been attributed to the headwaters of three different Peruvian rivers in the high Andes: the Marañón, the Apurímac, and the Mantaro. Explorers and scholars have identified each of the three rivers as being the source of the Amazon under one of the three definitions.
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.
This question actually refers to body parts: otoliths are small structures in your inner ears (in the semicircular canals, so this part is correct) that shift when you move - to help you sense your body position (so this part is also true).
But they're not exactly stones - they are small particles, so that's why the statement is false.
