Question

the mass of a body is 70kg. when completely immeresed in water ,it displaces 2000 cm³ of water. what is the relative density of the material of the body . please make it

Answer 1

1000cm^3=1 litre
2000cm^3=2litre

1000litre=1 m^3
2litre=0.002 m^3

density=mass%volume
70%0.002
=35000kg/m^3

Answer 2

$\textbf{\huge{ANSWER:}}$

Given:
Mass = 70 kg
Weight of water displaced = 2000${cm}^{3}$

Weight = 2000${cm}^{3}$

=》 2×${10}^{-3} {cm}^{3}$

Density of the substance = $\frac{70}{2 \times {10}^{-3}}$

=》 $35 \times{10}^{3}$

Relative Density = $\frac{Density\:of\:substance}{Density\:of\:water}$

=》 $\frac{35 \times{10}^{3}}{{10}^{3}}$

=》 $\textbf{35}$

Hope it Helps!! :)
