Question

Given the density of He = 0.179 kg/m^3 and density of air = 1.29 kg/m^3. What formulas can be used to calculate the volume (m^3) needed for the hot air balloon to lift at least 100 kg of load?

Calculate the volume (in m^3) of helium needed in a hot air balloon to lift at least 100 kg of load. Density of He = 0.179 k g/m^3, density of air = 1.29 kg/m^3 (Ans: 90) To solve the problem, which of the following equation/s can be use (check as many that best applies) dQ AS = O A,V1= A2V2 1 ]9192| F = 4 TTEO r2 F2 F1 A1 A2 O fEdA = 9 enc €0 O Q = mL Op = m/V O Q = mcAT E=F/q F P= A
