Find the mass of air and the overall specific volume
A 5 m3 container is filled with 900 kg of granite (density 2400 kg/m3 ) and the rest of the volume is air with density 1.15 kg/m3. Find the mass of air and the overall (average) specific volume.

On the moon the gravitational acceleration is approximately one-sixth that on the surface of the earth. A 5-kg mass is "weighed" with a beam balance on the surface on the moon.
The average length of life of a brand of light bulb is 2000 hours with a population standard deviation of 120. A sample of 100 light bulbs is to be taken. What is the probability of the sample mean being less than 2020 hours? P(xbar< 2020)
A positron (e+) in a thin wire can be considered as if in a 1- dimensional infinite potential well. Consider L = 0.005 mm length of the wire; (a) Determine the ground-state energy of a positron in such wire.
The other is moving upward at a constant velocity v2. If we consider the fluid Newtonian, solve for the velocity profile using our newlydefined Navier-Stokes Eqns.
A tank has two rooms separated by a membrane. Room A has 1 kg air and volume 0.5 m3, room B has 0.75 m3 air with density 0.8 kg/m3. The membrane is broken and the air comes to a uniform state. Find the final density of the air.
The plates of a Fabry-Perot interferometer have a reflection coefficient r = 0.99. Calculate the minimum resolving power R and the plate separation that will accomplish the resolution of the two components of the H-alpha doublet of the spectrum of
When you move up from the surface of the earth the gravitation is reduced as g = 9.807 - 3.32 × 10-6 z, with z as the elevation in meters. How many percent is the weight of an airplane reduced when it cruises at 11 000 m?.
