Answer

(a) Plimsoll line

Reason — Plimsoll line indicates the safe limit for loading the ship in water of density 103 kg m-3. A ship is not allowed to load further if its plimsoll line starts touching the water level, so that when it sails in sea water of density more than 103 kg m-3, only the part of it below the plimsoll line remains submerged in water.

Upthrust in Fluids

A weather forecasting plastic balloon of volume 15 m3 contains hydrogen of density 0.09 kg m-3. The volume of an equipment carried by the balloon is negligible compared to it’s own volume. The mass of the empty balloon alone is 7.15 kg. The balloon is floating in air of density 1.3 kg m-3. Calculate : (i) the mass of hydrogen in the balloon, (ii) the mass of hydrogen and balloon, (iii) the total mass of hydrogen, balloon and 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.
