Answer 2

Will the body weighing 120kg and having a volume of 0.03 sink in water?

To determine whether the body will sink or float in water, we need to compare the density of the body with the density of water. The density of an object is calculated by dividing its mass by its volume.

The density of water is approximately 1000 kg/m³ To find the density of the body, we can use the formula:

Density = Mass / Volume

Given that the mass of the body is 120 kg and the volume is 0.03 m³, we can calculate the density:

Density = 120 kg / 0.03 m³ = 4000 kg/m³

Comparing the density of the body (4000 kg/m³) with the density of water (1000 kg/m³), we can see that the body's density is greater than that of water. According to Archimedes' principle, an object will sink in a fluid if its density is greater than that of the fluid it is placed in.

Therefore, the body weighing 120 kg and having a volume of 0.03 m³ will sink in water.

Conclusion:

The body will sink in water due to its higher density compared to water.
