Answer:
The final temperature is T2= 5.35°C
Explanation:
Apply the Gay-lussacs's law we have
P1, initial pressure= 5.00 x 10^6 Pa
T1, initiation temperature= 25.°C
P2, final pressure= 1.07 x 10^6 Pa
T2, final temperature= ?
Cross multiplying and making T2 subject of formula we have
T2= 5.35°C
Answer:
Explanation:
The impulse-momentum theorem states the impulse on an object is equal to the change in momentum of that object. Momentum is given by . Since mass is constant, the train's change in momentum is:
(two significant figures).
Impulse is also given as , where
is the average force applied and
is change in time. Since
is given as
, we have the following equation:
(two significant figures).
