Answer:

Explanations:
The mass of the vessel, m = 74400 kg
The external diameter, d = 5.20 m
Radius, r = 5.2 / 2 = 2.6 m
![\begin{gathered} \text{Density of sea water, }\rho_w=1.025*10^3\operatorname{kg}m^(-3)^{} \\ \rho_w=1025\operatorname{kg}m^(-3) \end{gathered}]()
The volume of the vessel is given by the volume of a sphere

a) The buoyant force (B) is given by the formula:

b) The tension in the cable is given by the equation

Where T represents the tension
T = 739613.35 - 74400(9.8)
T = 10493.35
