Homework Answers
a) on increasing volume of the crate, the mass also increases hence the density of the material remained unchanged,
ratio = 1
=======
b)
as we know
density = mass / volume
for mass = constant
density is inversely proportional to volume
D' / D = V / V'
D' / D = L^3 / ( 2L)^3
D'/ D = 1/8
=======
do comment in case any doubt will reply will reply for sure.. Goodluck
