Answer:
is the density of the oil
Explanation:
Given:
- height of oil column,
- oil column height that is more than the water column height in the other arm,
<u>Now from the given it is clear that the height of water column is:</u>
Now according to the pressure balance condition of fluid columns:
Pressure due to water column = Pressure due to oil column
is the density of the oil
Answer:
Total displacement 155 m
Explanation:
From the question, the formula to apply will be that of cosine rule where:
where
a= 43 m , b=130m and c =? , <C=28° + 90° =118°
Substituting values in the equation as;
Answer:
1) 16.88 atm
2) 34.47 atm
Explanation:
Data:
Volume=0.700L
Temperature = 300K
Number of moles=0.480 mol
Ideal gas constant=0.082057 L*atm/K·mol
1) The ideal gas law is:
(1)
with P the pressure, T the temperature, n the number of moles, V the volume and R the ideal gas constant , so solvig (1) for P:
2) The vander Walls equation is:
solving for P
