Find the density of water if 300 m^{3} of water weigh 300 kg. (Given: Density = \frac{Mass}{Volume})
mass = 300 kg
Volume = 300 m3
Density = massvolume
= 300300 kg \ m3
= 1 kg / m3
Weight of 1m3 of sea water is lesser than the weight of fresh water of the same volume.
Density of sea water = 1.3g/cm3
Density of fresh water = 1g/cm3
A body of mass m is immersed in water with 3/4th of volume outside of water. Buoyant force acting on it is 1000N. Total volume of body is
( Take density of water as 1000kg/m3 and accelaration due to gravity as 10m/s2)
An object weighs 36g in the air and has a volume of 8.0 cm3. What will be it's apparent weight when immersed fully in water? Density of water = 1kg/ m3.
