A75.5-kg person puts on a life jacket, jumps into the water, and floats. the jacket has a volume of 3.38 x 10-2 m3 and is completely submerged under the water. the volume of the person's body that is underwater is 6.42 x 10-2 m3. what is the density of the life jacket?

Density of jacket will be

Explanation:

We know that weight of water displaced= buoyant force=weight of man

Now volume of water displaced

Density of water

So weight of water displaced

So weight of jacket = 98-75 = 23 kg

We have given volume of the jacket =

So density of jacket

answer; i believe the correct answer is (40,000 j) good luck

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
