A hotair balloon is inflated and its diameter is 10 ft. Assuming the balloon to be a sphere, determine the mass of air it contains in kg. Take the density of air as 1.2197 mg/cc
Prove that the density, specific weight and specific gravity of a substance are directly proportional to each other. Also calculate the density of pure water in kg/m3.
The atmospheric pressures at the top and the bottom of a building are read by a barometer to be 88.0 and 90.0 kPa. If the density of air is 1.0 kg/m3 and g = 9.81 m/s2, what is the height of the building?(Note: Show units check, answers without units will not be considered)
