Ответ:
A)
B)
Explanation:
= diameter of the spherical chamber = 5.50 m
Volume of the spherical chamber is given as
= density of the seawater = 1025 kg m⁻³
Part A)
Force of buoyancy by seawater on the chamber is given as
Part B)
= tension force in the cable in upward direction
= mass of the chamber = 87600 kg
Weight of the chamber is given as
Using equilibrium of force in the vertical direction, we have
