43.62m
Explanation:
Given parameters:
Energy = 8550J
Mass of bell = 20kg
Unknown:
Height of the bell = ?
Solution:
As this state, the bell possesses potential energy. Potential energy is the energy at rest in a body. It is due to the position of the body.
Potential energy = m g h
m is the mass of the body
g is the acceleration due to gravity of the body
h is the height of the body
The unknown is h and we should solve for it.
g = 9.8m/s²
Input the variables;
8550 = 20 x 9.8 x h
h = 43.62m

Answer : The fugacity in the solution is, 16 bar.
Explanation : Given,
Fugacity of a pure component = 40 bar
Mole fraction of component = 0.4
Lewis-Randall rule : It states that in an ideal solution, the fugacity of a component is directly proportional to the mole fraction of the component in the solution.
Now we have to calculate the fugacity in the solution.
Formula used :
where,
= fugacity in the solution
= fugacity of a pure component
= mole fraction of component
Now put all the give values in the above formula, we get:
Therefore, the fugacity in the solution is, 16 bar.
