To solve this problem it is necessary to apply the concepts related to density in relation to mass and volume for each of the states presented.
Density can be defined as

Where
m = Mass
V = Volume
For state one we know that




For state two we have to




Therefore the total change of mass would be



Therefore the mass of air that has entered to the tank is 6.02Kg

Answer:
The minimum diameter is 1.344 in
Explanation:
The angular speed of the driveshaft is equal to:

Where
N = rotational speed of the driveshaft = 2900 rpm

The torque in the driveshaft is equal to:

Where
P = power transmitted by the driveshaft = 134 hp = 73700 lb*ft/s

The minimum diameter is equal to:

Where
T = shear stress = 6100 psi
τ = 242.68 lb*ft = 2912.16 lb*in

Atoms are the smallest unit of matter.
There your answer!
