Aspherical submersible 1.87 m in radius, armed with multiple cameras, descends under water in a region of the atlantic ocean known for shipwrecks and finds its first shipwreck at a depth of 1.84 ✕ 103 m. seawater has density 1.025 ✕ 103 kg/m3, and the air pressure at the ocean's surface is 1.013 ✕ 105 pa.
(a) what is the absolute pressure at the depth of the shipwreck?
pa

(b) what is the buoyant force on the submersible at the depth of the shipwreck? (give the magnitude.)

The concepts that we need to apply in this problem are the Pressure in a liquid at a given depth, that is hydrostatic pressure and the force in terms of density, volume and gravity.

The hydrostatic pressure is given by,

Where

is the pressure at the top

is the density

g = gravity force

D = The distance from the top.

Part A )

Part B) The force in terms of density, volume and gravity is

gans

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
