Answer:

The arrows to the right of Earth should point up

Explanation:

The Earth acts as a huge magnetic dipole, oriented as its axis of rotation, with the North Pole located at the South geographic pole and the South pole located at the North geographical pole.

In a magnetic dipole, the lines representing the field go out from the north pole into the south pole.

This means that for the Earth, the field lines should go from south (which is the north magnetic pole) to north (which is the south magnetic pole): therefore, the arrows to the right of the Earth should point up as well as the line to the left.

Answer:

W = 1884J

Explanation:

This question is incomplete. The original question was:

Consider a motor that exerts a constant torque of 25.0 N.m to a horizontal platform whose moment of inertia is 50.0kg.m^2 . Assume that the platform is initially at rest and the torque is applied for 12.0rotations . Neglect friction.

How much work W does the motor do on the platform during this process? Enter your answer in joules to four significant figures.

The amount of work done by the motor is given by:

$W=\Delta K$
