Answer:
No, it is not necessary for them to have same mass.
Explanation:
Let both bodies have a density d1 and d2 respectively.
Since their volumes are equal V1 = V2
we know that,
density =
Hence, d1 = and d2 =
Taking the ratio of densities,we get
This implies that unless the bodies have same densities, the mass of the two bodies will not be same.
Answer:
maximimize the steel cause it would be safer.
Explanation:
its would be safer
DE = DC + CE
27 = 3v - 30 + 6v - 15
27 = 9v - 45
v = 8
