Question

A balloon of volume 2000 metre cube is filled with hydrogen of density 0.09 kg per metre cube the mass of the fabric is hundred kg the mass of the pilot is 70 kg what is the greatest mass of equipment that can be carried when operating in air of density 1.25 kg per metre cube(answer:2150 kg)

Answer 1

See on Math app Bro #

Answer 2

Answer:

look it can't be 2150kg ..as then it would have sinked ..answer should be 900 kg  

Explanation

amount of weight the air can hold =Vpg=1.25 *1000*g =1250 g

it can be equalled with=

mass of pilot +mass of fabric+mass of hydrogen filled in balloon+mass of equipment=70g+100g+2000(0.09)g +mg

therefore,1250=70+100+180+m

hence mass of equipment that can be carried m=900kg
