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.

THE ANSWER IS TRUE QUICK!!!!!!
Answer:
The role of rainforests in the water cycle is to add water to the atmosphere through the process of transpiration in which plants release water from their leaves during photosynthesis.
Explanation:
This moisture contributes to the formation of rain clouds, which release the water back onto the rainforest.

You didn't give the options and I couldn't find the exact question online. Let me try help out.
Incidence of tax is the impact that a tax simply has on how the economic welfare are being distributed. It refers to how tax is being distributed between the producers and the buyers of a particular good. It should be noted that the tax burden is shared by the sellers depending on the elasticity of the said product.
For example, in a situation whereby a $2 tax is imposed on each good a producer produces, if the producer then pass the tax to the final consumers when he raised the price of the goods by $2, we can simply say that such good has a price inelastic as the entire burden falls on the consumer.
Also, assuming the producer can't increase prices because such good is price elastic, that is, there will be a greater change in the quantity of the goods demanded, the burden will be felt by the producer alone. Here, we can say that the tax incidence falls on the producer.
