Title: hollow sphere of negligible mass and radius R is completely Post by: venous360 on Nov 4, 2014 hollow sphere of negligible mass and radius R is completely filled with a liquid so that its density is ρ. You now enlarge the sphere so its radius is 2R and completely fill it with the same liquid. What is the density of the enlarged sphere?
1- 4 ρ 2- ρ/2 3- ρ/8 4- ρ 5- 8 ρ Title: Re: hollow sphere of negligible mass and radius R is completely Post by: padre on Nov 4, 2014 Density = Mass/Volume
as mass remain same As Radius become 2 times ,volumme beomes ^3 = 8times So Density = p/8 Title: Re: hollow sphere of negligible mass and radius R is completely Post by: jim on Jan 7, 2022 https://biology-forums.com/index.php?topic=504199.0
