On october 21, 2001, ian ashpole of the united kingdom achieved a record altitude of 3.35 km (11 000 ft) powered by 600 toy balloons filled with helium. each filled balloon had a radius of about 0.54 m and an estimated mass of 0.27 kg. (a) estimate the total buoyant force on the 600 balloons.

buoyant force = 4.160  kN

Explanation:

given data

altitude = 3.35 km

toy balloon = 600

radius r = 0.54 m

mass m = 0.27 kg

to find out

total buoyant force

solution

we will apply here buoyant force formula that is

buoyant force for 600 = 600 × ρ × g × v    1

here v volume  = 4/3 × π × r³ = 4/3 × π × 0.52³ = 0.5889

and ρ = 1.20 kg/m³

so

buoyant force for 600 = 600 × ρ × g × v

buoyant force for 600 = 600 × 1.20 × 9.81 × 0.5889

buoyant force = 4160.06 N

buoyant force = 4.160  kN

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
