Answer:
The magnetic field reverses direction.
Explanation:
In astronomy, the Tully– Fisher relation (TFR) is an exact connection between the mass or characteristic radiance of a winding world and its precise speed or discharge line width. So the appropriate response is NO, there is no movement towards or far from us. For this situation, there is no Doppler effect we can quantify.
It is when the air hit the wave and it moves to another direction.
6 months with no sunrise and the other 6 without a sunset, at some places on Earth, are the result of the orientation of Earth's axis.
Qualitative data would be taken in this investigation. This is because the effect of the cold temperature on the leaves can not be measured quantitatively, but can be observed in the leaves' appearances. The qualitative data may include how green the leaf looks or how upright and rigid it is. The readings would be taken for leaves with and without snow.
