It is False in applying the pythagorean theorem to vector addition, the resultant vector is given by the perpendicular vector
<h3>What is Pythagoras theorem ?</h3>
A useful technique for figuring out the outcome of adding two (and only two) vectors that form a right angle to one another is the Pythagorean theorem. The technique cannot be used to combine more than two vectors or to combine vectors that are not at a 90-degree angle.
- The Pythagorean Theorem demonstrates how the side lengths of a right triangle can be calculated from the sum of the areas of three intersecting squares. This theorem is a very helpful tool that serves as the foundation for more intricate trigonometry ideas like the Pythagorean theorem's opposite.

Answer:
One observation would be the change in odor when observing the logs burning in a campfire and because of that a inference could be because a change in odor is occurring, a chemical change is happening to the logs (combustion).
A second observation would be that the wood being burned gave off smoke at first but then stopped and because of that a inference would be that the compound that were being burned creating the smoke was all evaporated from the wood.
Answer:
The relation is n = c/v where c is speed of light in a vacuum....v is the speed of light in the new medium ......n is the refractive index of the material
Answer:
7840 N
Explanation:
F = Nμ
F = mgμ
F = (2000 kg) (9.8 m/s²) (0.4)
F = 7840 N
