A iron cube of side 10 c m is kept on a horizontal table. If the density of iron is 8000 kg/m3. Find the pressure on the portion of the table where cube is kept
The dimension of wooden block is 2m X .25 m X .10 m. If relative density of wood is 0.6 calculate the mass of the block in kg
Differentiate between density and relative density
A 100 cm3 block has a mass of 395g. Find its relative density
A block of wood is kept on the table top. The mass of wooden block is 5 kg and its dimension are 40 cmX20cmX10 cm. Find the pressure exerted by the wooden block on the table if it made it lie on the table top with its sides of dimension
1) 20 cm × 10 cm
2) 40 cm × 20 cm
Take g=9.8 m/s2
