The Hindenburg was an airship. It had a very large hydrogen- filled balloon, with a volume of 140 000 m3. Below the balloon were heavy engines and room for cargo. The density of air is 1.20 kg/m3. The density of hydrogen is 0.09 kg/m3. c) What was the buoyant force on the balloon? d) What was the weight force of the hydrogen? e) If the balloon didn’t accelerate up or down, what was the total mass of the engines and cargo? Assume that the weight of the balloon fabric is negligible.
Solve C D E please
A barometer is used to measure air pressure. It is made of a tube of mercury (density of 13
500 kg/m3) in an open container. The top of the tube is sealed and contains a vacuum. The
bottom is open to the air.
During a storm, the mercury is observed to have a height of h = 0.70m.
