First we need to convert everything into SI units.
The initial volume of the gas is (keeping in mind that
:
The initial pressure of the gas is (keeping in mind that
:
The final pressure of the gas is (keeping in mind that
)
At constant temperature, the product between pressure and volume of the gas is constant, so we can write
from which we find the final volume of the gas:
Answer:
4v/3
Explanation:
Assume elastic collision by the law of momentum conservation:
where v is the original speed of car 1, v1 is the final speed of car 1 and v2 is final speed of car 2. m1 and m2 are masses of car 1 and car 2, respectively
Substitute 
Divide both side by 
, then multiply by 6 we have
So the final speed of the second car is 4/3 of the first car original speed
Answer:
A) An organism with favorable genetic variation will tend to survive and breed successfully.
Explanation:
In an ecosystem, organisms that don't have the best genetic variation will die off, leaving the more genetic favored ones to survive and become better as a whole.
Answer:
American athletes have won a total of 2,523 medals (1,022 of them gold) at the Summer Olympic Games and another 305 (105 of them gold) at the Winter Olympic Games, making the United States the most prolific medal-winning nation in the history of the Olympics.
Explanation:
Hope this helps! ^^
Answer:
B. Kinetic energy of the system is partially used up in the deformation of the vehicles.
Explanation:
In an inelastic collision, momentum is conserved, but kinetic energy is not. Kinetic energy is lost as heat or lost in the deformation of the objects.
