Sentences with phrase «spin axis orientation»

The formation of binary minor planets, tumbling action, and period change are most likely due to the YORP effect, which is a thermal process where absorbed sunlight, re-radiated as heat, can affect the minor planet's rotation period and even spin axis orientation.

In the case of the first set of products of possible spin - values, the orientation of the axes of the spin - measuring devices is the same; the angle between them is zero; and the cosine of this angle is one (1.0).

And that if you heat a magnet up enough, then you have no magnet at all: High temperatures randomly jumble all the bits of magnetic material (ultimately orientations of spinning electrons) that had aligned themselves along the north - to - south - pole axis.
