How many helium-filled balloons would it take to lift a person? Assume the person has a mass of 69 kg and that each helium-filled balloon is spherical with a diameter of 33 cm.
Alright Dude, If that worked
for you... dont forget to give THUMBS UP.(that will work for
me!)

If I missed something feel free to leave a comment.
atleast before giving downvote.
and, Thanks for using Chegg- Smarter way to study.

How many spherical 4’ diameter balloons are required to lift a 175-lb person and 25 pounds of equipment into the air at standard sea level conditions? Assume that each balloon has a mass of 250 grams. Barnard,
To know how many Helium balloons are needed to lift a girl who weighs 35 kg, one intends to measure how much weight a single balloon can lift. A scale that is sensitive to 0.1 g, small pieces of copper, and an ordinary party balloon show that a balloon with a volume of about 2 l can lift 2g of copper. How many balloons will it take to lift the girl? Does this agree with the result obtained if you...
1.) A balloon with 20 ft diameter is filled with Helium at STP (assume spherical shape volume is negligible) with a payload/lifting capacity of 130.86 kg. Take the same size balloon and fill with hot air this time. What must the internal temp be to lift the same mass?
A spherical balloon filled with helium gas must lift a1.00-kg scientific payload off the ground, and the mass of the empty balloon is 0.500 kg. The mass densities are 1.286 kg/m3 for air, 0.179 kg/m3for helium gas, 1.251 kg/m3 for nitrogen gas. Part A What is the minimum diameter of the balloon? Express your answer with the appropriate units. d = SubmitMy AnswersGive Up Part B A helium shortage forces the scientists to consider using nitrogen gas in the balloon....
A spherical balloon has a radius of 6.15 m and is filled with helium (pie- 0.179kg/m3). How large a cargo can it lift when such a balloon is in the air (Pair 1.29kg/m3), if the skin and structure of the balloon have a mass of 650 kg? Assume that there is no buoyant force on the volume of the cargo.
A spherical balloon has a radius of 7.65 m and is filled with helium. The density of helium is 0.179 kg/m3, and the density of air is 1.29 kg/m3. The skin and structure of the balloon has a mass of 930 kg . Neglect the buoyant force on the cargo volume itself. Determine the largest mass of cargo the balloon can lift.
Large helium-filled balloons are used to lift scientific equipment to high altitudes. What is the pressure, in atmospheres, inside such a balloon if it starts out at sea level with a pressure of one atmosphere and a temperature of 10.0 degree C and rises to an altitude where its volume is twenty times the original volume and its temperature is -48DegreeC ? What is the gauge pressure, in atmospheres, in the balloon then? (Assume the atmospheric pressure is constant.)
1 Balloons 60 cm Two similar helium-filled balloons tied to a 5 g mass float in equilibrium as shown in the diagram. There is a charge Q on each balloon (a) Draw a free body diagram of the mass and of each balloon three diagrams in total. Clearly label all of the forces in each diagram (b) Determine the charge Qon each balloon 5 g

A helium balloon ride lifts up passengers in a basket. Assume the density of air is 1.28 kg/m3 and the density of helium in the balloon is 0.18 kg/m3. The radius of the balloon (when filled) is R = 4.6 m. The total mass of the empty balloon and basket is mb = 124 kg and the total volume is Vb = 0.072 m3. Assume the average person that gets into the balloon has a mass mp = 71 kg...
