A balloon filled with hydrogen has a volume of 1 m3 and its mass is 1 kg. The volume of the block of a very light material which it can just lift is[Density of material of block is 91.3 kg/m² and that of air is 1.3 kg/m]11111)2)33004005006001 |

Answer» of block =91.3kg/m^3uplift from air =1.3kg×gDownforce from BALLOON =1kg×gSo, Extra weight that can be lifted =0.30gNSo, Considering buoyant force on itself,⇒0.30g+1.3vg=91.3vg [where V is Volume of the block]⇒0.3=90V⇒V= 1/300 m^3plz FOLLOW me and thank my ANSWERS ❤ |
