A 0.676 m long section of cable carrying current to a car starter motor makes an angle of 57.7º with the Earth’s 5.29 x 10^−5T f
Studentka2010 [4]

Answer:

The current in the wire under the influence of the force is 216.033 A

Solution:

According to the question:

Length of the wire, l = 0.676 m

\theta = 57.7^{\circ}

Magnetic field of the Earth, B_{E} = 5.29\times 10^{- 5} T

Forces experienced by the wire, F_{m} = 6.53\times 10^{-3} N

Also, we know that the force in a magnetic field is given by:

F_{m} = IB_{E}lsin\theta

I = \frac{F_{m}}{B_{E}lsin\theta}

I = \frac{6.53\times 10^{-3}}{5.29\times 10^{- 5}\times 0.676sin57.7^{\circ}

I = 216.033 A

The moon clearly exhibits a light and dark portion during most of the month except during full moon. What causes the dark portio
mylen [45]
While rotating around Earth the Moon also rotates around it's axis. These two rotations have almost same duration (27.3 and 27 days respectively). This is the reason why we always see the same side of Moon.

The dark part of a Moon is the part where there is night on the Moon, meaning there is no sunlight visible. This dark part depends on the Moon's position relative to Earth and Sun. The change in size is due to part of Moon-day. Dark part of Moon has night, bright part has day and the boundary has either sunrise or sunset.
