1.
An object floats in a liquid if its density is
greater than that of the liquid
equal to zero
twice that of the liquid
less than that of the liquid
2.
A solid has density 1200 kg/m3. In water (1000 kg/m3) it will
float
sink
neither
become lighter
3.
A steel ship floats because
steel is less dense than water
it has no weight
its average density is less than that of water
the sea is salty
4.
A floating boat has weight 5000 N. The upthrust on it is
5000 N
less than 5000 N
more than 5000 N
zero
5.
The same ship moves from the sea into a freshwater river. It will
float higher
float lower
be unchanged
sink immediately
6.
A mass of 0.45 kg occupies 5.0 × 10−4 m3. In water this object will
sink, because its density is 900 kg/m3
sink, because its density is 2250 kg/m3
float, because its density is 1100 kg/m3
float, because its density is 900 kg/m3
