Answer:
Explanation:
The force required to submerge something underwater can be found from Archimedes principle:
FB=pwVg
Where FB is the buoyant force, pw is the density of water (1g/ml), V is volume of the water displaced, and g is gravity. The key here is V. The volume of water displaced by the cork is equal to the volume of cork. Therefore, the required force is
F=1 g/cm³ x 10 cm³ x 9.8 m/s²= 98 N
