Answer
The Sun spins on its axis in a way similar to the Earth revolving to give us day and night. Also, it 'wobbles' as the planets orbit it, in the same way your washing machine wobbles if the load is unbalanced.

Answer:
The answer is A
Typhoons are basically like hurricanes, formed by weather and climate.
Tornados are formed by weather activity.
Floods can happen from weather or tectonic activity, but its more of an indirect effect rather than a direct one.
Earthquakes are from tectonic activity, the right of fire is the boundary of a tectonic plate.
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.
