Explanation:
point c is minimum Amplitude in transversal wave
Answer:
50.67
Explanation:
L = 4 m

Let the mass of small length dx is dm.
So, dm = ρ(x) dx
Integrate on both the sides within proper limits

![m = \left [ 10x+\frac{4}{3}x^{\frac{3}{2}} \right ]_{0}^{4}](https://tex.z-dn.net/?f=m%20%3D%20%5Cleft%20%5B%2010x%2B%5Cfrac%7B4%7D%7B3%7Dx%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%20%5Cright%20%5D_%7B0%7D%5E%7B4%7D)
m = 40 + 32 / 3 = 152 / 3 = 50.67

We use them to survive, such as for oxygen, food, and shelter.
That n2 = 2*n1. That is, the index of refraction is twice as big in medium 2 since v=c/n
