Answer:
The two waves will add vectorially to produce a small amplitude wave in a valley phase.
Explanation:
The two waves will add vectorially to produce a small amplitude wave in a valley phase. This is because the amplitudes of the waves are slightly different and in opposite directions. When wave 1 cancels out all of wave 2, the resultant wave would be the slight difference between both waves, and it would be in the direction of wave 1 which is a valley phase.
The total charge on the helix is
- Q =

Height of one turn = 
Horizontal distance in one turn = 
<h3>
length of spring in one turn is</h3>

So, the total length of spring

Therefore, charge on spring

B. physics and engineering
Explanation:
Biomechanics is the study of mechanical laws and living organisms. Hence, it comprises of the interrelationships between physics and engineering.
The answer is Anxiety. Hope this helps.
Answer:
Law of conservation of momentum states that "The total momentum of an isolated system always remains constant"
Or
"In an isolated system the total momentum of the interacting bodies remains constant before and after collision or interaction".
