Answer:
d = 0.743 g/cm³
Explanation:
Given data:
Mass of cylinder = 65.34 g
Height = 15.60 cm
Radius = 1.34 cm
Density of cylinder = ?
Solution:
Volume of cylinder:
V = πr²h (π = 22/7)
V = 88 cm³
Density of cylinder:
d = m/v
d = 65.34 g / 88 cm³
d = 0.743 g/cm³
So that we have the right answer once we do the addition
Say that I measure my self at 12 feet with one measuring stick, and go on with another measuring stick that tells me I'm 3 meters tall, if I added those, I would be at something like 15/46 or something like that. See that would be wrong. We would want the right denominator so that it could be easier and also correct.

Answer:
The Volume of the lungs that would produce 2 mmHg pressure decrease is
Explanation:
From the question we are told that
The volume of air in the lungs is 
The pressure difference for quit normal inspiration is 
The temperature of air in the lungs 
The pressure after normal expiration is at 
From ideal gas law we have that
Now since nRT is constant we have that
As the pressure decreased by 2 mmHg the volume becomes
