A body X sinks in water, but a body Y floats on water. The density of the body X is ......... than the density of body Y.
Explain the meaning of the statement
‘Relative density of aluminium is 2.7’.
The density of water is 1.0 g Cm-3. The density of iron is 7.8 × 10″3 g Cm-3. The density of mercury is 13.6 g Cm-3.
Answer the following:
Will a piece of iron float or sink in mercury?
Define the term thrust. State its S.I. unit.
Explain the following statement:
It is easier to cut with a sharp knife than with a blunt one.
A simple U tube contains mercury to the same level in both of its arms. If water is poured to a height of 13.6 cm in one arm, how much will be the rise in mercury level in the other arm?
Given : density of mercury = 13.6 x 103 kg m-3 and density of water = 103 kg m-3.
