An undersea research chamber is spherical with an external diameter of 5.50 m . the mass of the chamber, when occupied, is 87600 kg . it is anchored to the sea bottom by a cable. the density of seawater is 1025 kg/m3.part a what is the buoyant force on the chamber? express your answer to three significant figures and include the appropriate units. part b what is the tension in the cable? express your answer to two significant figures and include the appropriate units.

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

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
