Explanation: While most of Latin America speaks Spanish, in Haiti, people speak French and Brazil, people speak Portugese. Both nations played a role in getting their independence. Also, the fact that both French and the Portugese exported slaves from West Africa to the West Indies which is what we call the Carribean today.
Hope this clarifies your question.
You have a formula :
. You just have to apply it. It would gives :
Now, use your mind. How many would be needed to make 2000 cm3.
Therefore <span>the minimum number of identical containers that Tim would need to make 2,000 cm3 of ice is
20 (
option D).
Hope this helps !

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 scientific method is a method of investigation involving experimentation and observation to acquire new knowledge, solve problems, and answer questions. The key steps in the scientific method include the following: Step 1: Make observations. Step 2: Formulate a hypothesis.
