Answer:

The length of the wire is 579 m

Explanation:

Given;

current on the wire, I =  11.3-mA

magnetic field of the wire, B = (16.2i + 2.4 ĵ) T

Magnitude of force experience by the wire, F = 15.7 N

Magnitude of force experience by  current carrying wire at a given a magnetic field strength is calculated as;

F = BILsinθ

Where;

B is magnitude of magnetic field

F is the force on the wire

L is length of the wire

θ is direction of the magnetic field

B = \sqrt{16.2^2 +2.4^2} = \sqrt{268.2} = 16.377 \ T

tan \theta = \frac{2.4}{16.2} \\\\tan \theta =  0.1482\\\\\theta = tan^{-1}(0.1482) \\\\\theta = 8.43^o

Length of the wire is calculated as;

L = \frac{F}{BIsin \theta} = \frac{15.7}{16.377*11.3*10^{-3}*sin(8.43)} = 578.9 \ m

Therefore, the length of the wire is 579 m

Answer:

You could move something across the Earth with a little push. It would make fuel really efficient on those pathways. You could make a floor that is impossible to walk on. Everybody would just fall without traction.

A box with a mass of 7 kilograms is pushed up a ramp to a height of 5 meters. What is the work done against the force of gravity
muminat
The potential energy of the box when it gets to the top is

                  (mass) (gravity) (height)

             =    (7 kg) (9.8 m/s²) (5 m)

             =          343 joules.

That's the work done against the force of gravity.  Any
additional work is done against the force of friction.
