A compound is formed due to the chemical combination or chemical reaction between two or more elements. The elements forming a compound cannot be separated by physical means. The properties of the compound is different from the properties of the elements forming it.
Based on this, the answer would be:
They are different.
The frequency<span> of oscillation of the dot is the </span>frequency<span> #f# of the </span>wave<span>. The second </span>wave<span> has twice the </span>frequency<span> of the first. </span>You<span> can see that the </span>wavelength<span>is halved when the </span>frequency<span> is doubled. Since #v# is constant, </span>if<span> #f# increases, #λ# must decrease, and vice versa</span>
Answer:
a
The total distance traveled is 
b
The average velocity is 
Explanation:
From the question we are told that
The time taken for first part 
The speed for the first part is 
The time taken for second part is 
The speed for the second part is 
The time taken for third part is
The speed for the third part is 
Generally

Therefore the total distance traveled is

substituting values


Generally the average velocity is mathematically represented as

Where
is the total time taken which is mathematically represented as


The average velocity is
