(2009? Jingjiang City simulation) The figure is a national traditional sports "one bamboo rafting" performance scene. If the performer under the feet of the bamboo mass of 10kg
(1) the person and the total gravity of the bamboo: G = G people + G bamboo = 500N + 10kg × 10N / kg = 600N;
=
=0.06m3;
Because the person and the bamboo floating in the water, buoyancy F = G = 600N;
(2) by Archimedes' principle of buoyancy = ρgv row: v row =
| F buoyancy |
| ρg |
| 600N |
| 1.0×103kg/m3×10N/kg |
So the answer is: buoyancy; 600; 0.06.
