The deepest part of the atlantic ocean is called milwaukee deep with a depth of 8648 m. determine the pressure in the ocean water at the base of milwaukee deep.

8.475 x 10^7 Pa

Explanation:

h = 8648 m, g = 9.8 m/s^2, density of water, d = 1000 kg/m^3

Pressure at a depth is defined as the product of depth of water , acceleration due to gravity and density of water.

P = h x d x g

P = 8648 x 1000 x 9.8 = 8.475 x 10^7 Pa

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.

need to see circuit to get time constant
