Alpha Ursae Minoris, or Polaris, has a magnitude of 1.97. It is also a Population I (high metal content, like our sun) Cepheid variable star, which means its magnitude changes over a certain period (though the change is minor).

Consider a pair of forces one having a magnitude of 20 N and the other a magnitude of 12N What maximum net force is possible for these two forces what is the minimum net force prossible?
The min net force magnitude you can have is (20 - 12) = 8 N, when the two forces are directly opposite in directions. When the two forces align, the net force magnitude becomes the maximum, which is equal to (20 + 12) = 32 N. You can guess that the net force magnitude is somewhere between 8 N and 32 N, when the two forces are at an angle other than 0o or 180o. Let us say the larger force is A and the smaller force is B, at an angle, alpha, to one another. Then the net force magnitude, |C| = |A| + |B|*cos(alpha). The magnitude of C, |C|, depends solely on cos(alpha), since |A| and |B| are fixed. When alpha = 0o, |C|= |A| + |B| (maximal); when alpha = 180o, |C|= |A| - |B| (minimal). Note that max(cos(alpha))=1 and min(cos(alpha))=-1. ================================
