Explanation:
It is known that the molecular weight of ammonia (
) is as follows.
Molecular weight () = 
= 17
(a) Therefore, we will calculate the mass as follows.
= 8500 g
Now, formula to calculate weight of the system in N is as follows.
Weight = mass × g
= 
= 83.3 N (1 
= 1 N)
Hence, the weight of the system is 83.3 N.
(b) Relation between specific volume and number of moles is as follows.
Therefore, calculate the specific volume as follows.
= 12 
Also,
v = 
= 0.705882 
Therefore, we can conclude that the value of specific volume is 12 and 0.705882 .
The vertical acceleration of the yo yo cent of mass is 0.66 m/s².
We know that, T = M*a
And T is given as 2M/3
2M/3 = M*a
So, a = 0.66 m/s²
What is Acceleration ?
Acceleration is the general term for any process where the velocity changes. There are only two ways to accelerate either by increasing the speed or decreasing direction, or both. The reason for this is that velocity includes both a speed and a direction.
You cannot possibly be accelerating if you don't also change you direction and speed, regardless of how swiftly you are travelling. Due to this, a jet experiences no acceleration even when it is moving at a high speed. In this case, 800 miles per hour, because its velocity is constant.
When it lands, the jet will accelerate as it slows down and quickly come to a stop.

Answer
To understand this concept it is necessary to understand Newton's Second Law
According to Newtons Second law applied force is equal to rate of change of momentum of a body.
Mathematically,
here, 
is rate of change of momentum with respect to time
It means If two eggs fall from same height,one on softer surface and other on hard surface that time the momentum of both eggs will remain equal at both the surfaces. But, impact time will be different. On hard surface egg will stop almost instantly so impact time will be small and hence the force on egg will be large therefore the egg will breakup.
On the other hand on the soft surface like a cotton, egg will not stop instantly but it will slow down for a few seconds and then stop due to which the time of impact will increase. Therefore the force on egg will be less and it won't break up.
