Name two geographic obstacles and one political obstacle that stood in the way of the construction of the Panama Canal.

Answer: The two geographic obstacles that stood in the way of the construction of the Panama Canal was that Panama was very mountainous, and there were a lot of mud slides. One political obstacle was that Panama was part of Colombia. The united states had to negotiate with Colombia before Panama became independent. Engineers had to build a dam, design and build locks, and remove huge amounts of earth and rock in order to overcome the geographical obstacles.

I hope it helps, Regards.

it is possible for two stars to have different temperatures and different sizes but the same luminosity. explain how.
Darina [25.2K]

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.
