Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction. The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series
There are different reasons for ranking. The Rank order of the vendors that best meet Amazon’s goals are;
Vendor E - 1st
Vendor R - 2nd
Vendor K - 3rd
Vendor F - 4th
<h3>Why Vendor E ranking first?</h3>
Vendor E is first because it has low cost issues, low quantity, high shipped on time and low cost to amazon. This is said to fit about 100% of parameters.
Vendor K is known to have low cost issues, moderate quantity shipped, high quantity shipped and high cost to amazon.
A long string can be easily stretched. The Two points on the string are labeled A and B is that A should be at 90 degrees with same magnitude and B should be at 270 degrees with same magnitude.
<h3>What is Angle magnitude</h3>
This is known as the amount of rotation via which one of the arms is said to be rotated about vertex to result in a given position of the other.
Equal vectors are known to have the same magnitude and direction. Two vectors are said to be equal when their magnitude and direction are said to be same.
See the full question below
A long string is stretched and its left end is oscillated upward and downward. Two points on the string are labeled A and B.At the instant shown, orient v(A) and v(B) to correctly represent the direction of the wave velocity at points A and B.At each of the points A and B, rotate the given vector to indicate the direction of the wave velocity.Figure:A string is attached and moving up and down
