A ballon weighing `50 kg` is filled with `685kg` of helium at `1atm` pressure and `25^(@)C`. What will be its pay load if it displaced `5108 kg` of air ?

A ballon of diameter 20 metre weighs 100 kg Calculate its pay-load if its is filled with He at 1.0 atm and 27^(@)C Density of air is 1.2 kg,^(-3) [ R =0.082 dm^(3) atm K^(-1) mo1^(-1)] .

A balloon of diameter 21 meter weight 100 kg. Calculate its pay-load, if it is filled with He at 1.0 atm and 27^(@)C . Density of air is 1.2 kg m^(-3) . (Given : R=0.082 L atm K^(-1)mol^(-1) )

A solid weighs 6 kg in air. If its density is 2000 "kg" m^(3) what will be its apparent weight in water?

A man weighing 100 kg carriesa load of 10kg on his head. He jumps from a tower with the load on his head. What will be the weight of the load as experienced by the man?

Pay load is defined as the difference between the mass of displaced air and the mass of the ballon Calculate the pay-load when a balloon of radius 10m mass 100 kg is filled with helium at 1.66 bar at 27^(@)C (Density of air = 1.2 kg m^(-3) and R = 0.083 nar dm^(-3) K^(-1) mo1^(-1) ) .
