Q:

What does the judicial branch do?

Answer

The United States government has 3 branches, which all serve an important role in running the government and keeping our system of laws in place.


 


1. The legislative branch


2. The executive branch 


3. The judicial branch


 


The legislative branch makes the laws while the executive branch enforces these laws. 


The judicial branch is a system of courts that applies the laws.


 


Both the federal government and each of the 5 states have individual judicial branches which all serve this purpose.


 


For example :: 


If the federal government were like a basketball game, the judicial branch is much like the referee that helps settle disputes. The executive branch and the legislative branch are often like the players in the game trying to score points against each other, and the judicial branch is there to clarify the rules and make sure each side is acting fairly.

Q:

At what temperature do the Fahrenheit and celcius scales give the same reading?

A) 212 degrees B) 32 degreees
C) -40 degreees D) 0 degreees
 
Answer & Explanation Answer: C) -40 degreees

Explanation:

We want the temperature when F=C.

We know that, F = C x 95 + 32

So substituting C For F, we have C = -40o

Therefore,  C = -40. 

Thus when C = -40, we have C = F

Which law relates to the ideal gas law?

A) P1T1 = P2T2 B) P1/V1 = P2/V2
C) P1V1 = P2V2 D) T1/V1 = T2/V2
 
Answer & Explanation Answer: C) P1V1 = P2V2

Explanation:

Ideal Gas Law ::

The Combined gas law or General Gas Equation is obtained by combining Boyle's Law, Charles' Law, and Gay-Lussac's Law. It shows the relationship between the pressure, volume, and temperature for a fixed mass (quantity) of gas:

P1V1T1 = P2V2T2

 

Hence, the Boyle's law P1V1 = P2T2, relates to ideal gas equation.
