A weather forcecasting plastic balloon of volume `15m^(3)` contains hydrogen of density `0.09kgm^(-3)`. The volume of an equipment carried by the balloon is negligible compared to its own volume. The mass of empty balloon alone is 7.15 kg. The balloon is floating in air of density `1.3kgm^(-3)`. Calculate (i) the mass of hydrogen in the balloon. (ii) the mass of hydrogen and balloon, (iii) the total mass of hydrogen, balloonand equipment if the mass of equipment is x kg. (iv) the mass of air displaced by balloon and (v) the mass of equipment using the law of floatation.
