The mass of a bottle filled with water is found to be 150 g. the mass of the empty bottle is 50 g and the external volume of the container is 125 `cm^(3)`. Find out the density of the material of the bottle.

The mass of a density bottle when it is filled with a liquid of density 3000 kg m^(-3) is 400 g and the mass of the bottle when it is filed with water is 200 g. The mass of the empty density bottle when it is filled with water is 200 g. The mass of the empty density bottle is "_____" g.

The mass of a density bottle when it is filled with a liquid of density 3000 kg m_(-3) is 400 g and the mass of the bottle when it is filled with water is 200 g. The mass of the empty density bottle is "__________" g.

A bottle of water is (3)/(7) th full. This water is poured into another bottle which is now (2)/(3) rd full. Find the ratio of the volume of the first bottle to the volume of the second bottle.

An empty plastic bottle is kept and three holes are made in it at the same height from the bottom of the bottle. Bottle is now filled with water. Water stands leaking out 'from the holes. Do the different stream of water coming out of the holes fall at the same distance from the bottle? What conclusion do you draw ?
