Answer:
change in internal energy 3.62*10^5 J kg^{-1}
change in enthalapy 5.07*10^5 J kg^{-1}
change in entropy 382.79 J kg^{-1} K^{-1}
Explanation:
adiabatic constant
specific heat is given as
gas constant =287 J⋅kg−1⋅K−1
specific heat at constant volume
change in internal energy
change in enthalapy
change in entropy
Answer:
B) the change in momentum.
Explanation:
The impulse is defined as the product between the force applied on an object (F) and the duration of the collision ():
(1)
We can rewrite the force by using Newton's second law, as the product between mass (m) and acceleration (a):
So, (1) becomes
Now we can also rewrite the acceleration as ratio between the change in velocity and change in time: . If we substitute into the previous equation, we find
And the quantity is equivalent to the change in momentum,
.
