The second statement is false. The Sun is a star, but not the only star.
Answer:
<em>The resultant velocity has a magnitude of 38.95 m/s</em>
Explanation:
<u>Vector Addition</u>
Given two vectors defined as:


The sum of the vectors is:

The magnitude of a vector can be calculated by

Where x and y are the rectangular components of the vector.
We have a plane flying due west at 34 m/s. Its velocity vector is:

The wind blows at 19 m/s south, thus:

The sum of both velocities gives the resultant velocity:

The magnitude of this velocity is:


d = 38.95 m/s
The resultant velocity has a magnitude of 38.95 m/s
Answer:
The hydrosphere, the sphere of influence that deals with water in its various forms (some separate out ice and call that the cryosphere), provides the biosphere with a much needed component....water. Life would not exist as we know it without water. It places in important role for all organisms, alongside playing an important role in various earth processes.
