Answer:
I think it's a true but I'm not the smartest
Answer:
Explanation:
(a)
Since the earth is assumed to be a sphere.
Volume of atmosphere = volume of (earth +atm osphere) — volume of earth
Hence the volume of atmosphere is
(b)
Write the ideal gas equation as foll ows:

Hence the required molecules is 
(c)
Write the ideal gas equation as follows:
Hence the required molecules in Caesar breath is
(d)
Volume fraction in Caesar last breath is as follows:
(e)
Since the volume capacity of the human body is 500 mL.

Answer:
zero
Explanation:
For the box remaining at rest, the total acceleration on the box must be zero. Since force F = m*a, the force F must also be zero.
