If the relative density of ice is 0.9, its density is _________ kgm3.
0.9
900
9000
9
Given data :
The relative density of ice is 0.9
The density of ice=?
Formula:
Realativedensity=densityoficedensityofairdensityofair=1000kgm3
solution:
0.9=densityofice1000densityofice=0.9×1000kgm3densityofice=900kgm3
So, the correct option is C.
If the ratio of the density of ice to that of wood is 98and the relative density of ice is0.9, then the density of wood is _____kgm-3(Take the density of water=103kgm-3).)
If (velocity)x=(pressure)32×(density)-32, then x would be ______.
Calculate the volume of a big block of brass having mass 340kg. Density of brass 8500kgm3.
The volume of 50g a substance is 20cm3. Find its density. If the density of water is1gcm3, will the substance float or sink.
Calculate the time for which a motor pump of 10HP and efficiency 80% must be switched on, so as to pump 20m3 of water through a vertical height of 20m. [Density of water = 1000kgm3, g=10ms2, 1HP=750W]
