This question involves the concepts of the law of conservation of momentum.
The magnitude of the final momentum of the eight ball is "0.22 N.s".
According to the law of conservation of momentum:
where,
= initial momentum of the cue ball = 0.23 N.s
= initial momentum of the eight ball = 0 N.s (since ball is initially at rest)
= final momentum of the cue ball = 0.01 N.s
= final momentum of the eight ball = ?
Therefore,

Answer:
gas is dioatomic
T_f = 330.0 K
Explanation:
Part 1
below equation is used to determine the type Gas by determining value
where V_i and V_f is initial and final volume respectively
and P_i and P_f are initial and final pressure
\gamma = 1.38
therefore gas is dioatomic
Part 2
final temperature in adiabatic process is given as
substituing value to get final temperature
T_f = 330.0 K
Part 3
determine number of moles by using following formula
Answer:
The energy which is expend by the person is .
Explanation:
The formula for the potential energy due to the height of the object is as follows as;
U= mgh
Here, h is the height of the person, m is the mass of the object and g is the acceleration due to gravity.
It is given in the problem that a person is 8850 m above the sea level. 78 kg climber would expend energy against the gravitational force in climbing to the summit from sea level. Here, the person has potential energy as he is above the sea level.
Put h= 8850 m, m= 78 kg and and in the above expression to get the value of energy.
U= (78)(9.8)(8850)
U= 6764940 J
Therefore, the energy which is expend by the person is .
