What is the buoyant force on a helium balloon in air if the balloon is spherical with diameter 18.0 cm ?

Solutions

Expert Solution

density of air = 1.293 kg/m3 , volume of helium balloon =4/3r3 =4/3*3.14*(0.09)3= 0.034 m3

buoyant force on a helium balloon in air =density of air * volume of helium balloon*g

                                                          =1.293*0.034*9.8= 0.43 N

Sharks are generally negatively buoyant; the upward buoyant force is less than the weight force. This is one reason sharks tend to swim continuously; water moving past their fins causes a lift force that keeps sharks from sinking. A 92 kgbull shark has a density of 1040 kg/m3. What lift force must the shark's fins provide if the shark is swimming in seawater? Bull sharks often swim into freshwater rivers. What lift force is required in a river?

.A balloon holds 36.7 kg of helium. What is the volume of the balloon if the pressure is 1.14 atm and the temperature is 23 °C? 2.STP (standard temperature and pressure) is used as a reference point for the molar volume of an ideal gas. In the USA, most chemists, most general chemistry texts, and OWL use STP = 0°C, 1 atm, where the molar volume = 22.4 L/mol. If the reference pressure is chosen to be 1 bar, the...

A person is about to take off in an air balloon, full of helium, can be considered as a sphere with a radius of 7.5 m. The basket and balloon material have a combined mass of 314 kg. The balloon is kept from moving up by a certain amount of ballast, in the form of sandbags, which provides its own weight. The person has a mass of 125 kg. Helium has a density of 0.18 kg/m3, while air has a...
