Aspacecraft in the shape of a long cylinder has a length of 100 m, and its mass with occupants is 1490kg. it has strayed too close to a black hole having a mass97 times that of the sun. the nose ofthe spacecraft points toward the black hole, and the distancebetween the nose and the center of the black hole is 10.0 km.

(a) determine the total force on thespacecraft.
(b) what is the difference in the gravitational fields acting onthe occupants in the nose of the ship and on those in the rear ofthe ship, farthest from the black hole? this difference inacceleration grows rapidly as the ship approaches the black hole. it puts the body of the ship under extreme tension and eventuallytears it apart.

To develop this problem, it is necessary to apply the concepts related to the Gravitational Force and its respective change related to the black hole.

Gravitational Force are given as

Where

l = Length

R = Separation between both

M = Mass of Object

m = mass of block hole

G = Gravitational Universal constant

Our values are given as

l = 100m

M = 1490

is mass of sun

R = 10km

PART A ) Replacing in our equation we have that

PART B) The difference at this force would be given as

As Force is equal to mass and gravity then

found in the nucleus

has mass of one amu

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.
