Physics Help!!! A sealed chamber, totally submerged, is anchored to the ocean floor…..?
If the chamber has a mass of (2.5*10 to the 7th kg) and a volume of (2.8*10 to the 4th meters cubed)
What is the buoyant force on the chamber?
What is the tension in the anchor chain holding the chamber under water?
I don’t just want the answers, I want to know how to do it
Thanks!!!!!
the buoyant force is the weight of displaced water; the weight of the water displaced by this volume is
weight of water = m g = rho V g
where rho is the density of water=1000kg/m^3
and V is given as 2.8×10^4 m^3
so Fbuoyant = weight water displaced = 1000kg/m^3×9.8m/s/s x 2.8e4 m^3
Fb = 2.74e8N
the tension in the chain pulls down, as does gravity, so newton’s second law applied to the chamber is
Fb-mg-T =0
T=Fb-mg = 2.74e8N - 2.5e7kg x 9.8m/s/s
T=2.9e7N
