The purpose of this passage is to clarify what a UFO is. The passage tells you that even though UFOs often star in science fiction movies, most UFOs are actually aircraft, kites, clouds, meteors or rocket debris. It also cites a famous case in order to provide evidence for their claim.
There are many groups of people who had arguments and challenges with each other. These problems have occurred in Bible times up to today. The reasons why they have the troubles they do can be for many reasons such as racial discrimination, religious differences, social standings, age gaps, medical ideas, and many more! One example is the segregation that occurred between African Americans and Whites. This had a few motivations like control, superiority, past ideas and ways, and convinience.
Any vector in the xy-plane has the form v = c1i + c2j + 0k
For v to be perpendicular to a, we need v · a = 0
So, 3c1 - 5c2 = 0
For example, choose c1 = 5 and c2 = 3.
Then v = 5i + 3j + 0k is perpendicular to a.
ll v ll = √[52 + 32 + 02] = √34
A unit vector in the xy-plane that is perpendicular to 3i - 5j + k is:
u = v / llvll = (5/√34)i + (3/√34)j + 0k
