Question

Volume of an object is 20 cm^3 and the mass in 50 g. density of water is 1gcm^-3. will the ocject float on water or in dink

Answer 1

Mass = 50g
Volume = 20 cm^3
Density = m/v = 50/20 = 2.5 g/cm^3

Since its density is more than density of water, it will sink in water.

Answer 2

Hey !!

Here is your answer...

Given,

$mass = 50 \: g$

$volume = 20 \: {cm}^{ - 3}$

$density = \frac{mass}{volume} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{50}{20} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2.50 \: {g \: cm}^{ - 3}$

So the density is more than that of water therefore it will sink.

Hope it helps..
