The captain of a plane wishes to proceed due west. thecruising speed of the plane is 245 m/s relative to the air. aweather report indicates that a 38.0-m/s wind is blowing from thesouth to the north. in what direction, measured with respectto due west, should the pilot head the plane relative to theair?

South-West direction

Explanation:

Let  be velocity of the plane relative to the air,  be velocity of the air relative to the ground,  is the velocity of the plane relative to the ground

therefore,

From the triangle attached, the angle characteristics to the direction of relative velocity of the plane can be found

 South-West direction

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
