Answer:
mass = 25.5kg
Explanation:
The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g equal to the value of gravitational acceleration on Earth, g, of about 9.8 m/s².
Mass, m =
Answer:
Explanation:
Joule -Thompson effect
Throttling phenomenon is called Joule -Thompson effect.We know that throttling is a process in which pressure energy will convert in to thermal energy.
Generally in throttling exit pressure is low as compare to inlet pressure but exit temperature maybe more or less or maybe remains constant depending upon flow or fluid flow through passes.
Now lets take Steady flow process
Let
Pressure and temperature at inlet and
Pressure and temperature at exit
We know that Joule -Thompson coefficient given as
Now from T-ds equation
dh=Tds=vdp
So
⇒
So Joule -Thompson coefficient
This is Joule -Thompson coefficient for all gas (real or ideal gas)
We know that for Ideal gas Pv=mRT
So by putting the values in
For ideal gas.
Answer:
Christian
Explanation:
Given that
Force applied by Sean ,F₁=100 N
Force applied by Christian ,F₂=200 N
Lets take mass of the box = m kg
As we know that from second law of Newton's
F= m a
F=Force,m=mass ,a=acceleration
From the above we can say that acceleration a₂ is greater than a₁ is for the same mass of the box.
Therefore Christian will acceleration more for the box.
