Question

A metal spear of mass 200g displaces 10 ml of water find the density of the spear in kg per meter cube

Answer 1

Answer: 20000 kg/ m 3

Explanation:

Mass (m)=200 g=0.2 kg

Volume=10 ml= 10 cm 3= 10^-5 m 3

ATP, Density (d)= Mass (m)/ Volume (v)

=  0.2 kg / 10^-5= 20^4 kg/m 3

I hope the answer is satisfactory.
