A scuba diver and her gear displace a volume of 67L and have a total mass of 70kg. What is the buoyant force?
on the diver in sea water?
Buoyant force
= weight of water displaced
= 67 * 1.025 * 9.8 (The average density of seawater at the surface of the ocean is 1.025 g/mL)
= 673 N.
Is there something to help breath under water besides scuba gear and a snorkal?
