The answer is A)100m : 0m
The pool is 50m long
so she swam from the two ends of the pool two times
so in total she swam 50x2 m which is 100m
and she she displaced no meters because she ended in the same point as where she started
The dark spots on the moon are the craters and there light spots are made up of the moon dust technically called regolith
Answer:

Explanation:
Given:
Length of cylinder is, L = 0.27 m
Outer radius of cylinder is, r_out = 1.12×10^{-2} m
Inner radius of cylinder is, r_in = 3.9×10^{-3} m
Mass of person, m = 60 kg
Young's modulus , Y = 9.4×10^9 N/m2
(a)
Compressional strain of humerous is,



![= \frac{(60 kg)(9.8 m/s2 )}{(\pi)[( 1.12\times 10^{-2})^2 - (3.9\times 10^{-3} m)^2] (9.4\times 10^9 N/m2 )}[tex] [tex]= 1.80\times 10^{-4} m](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B%2860%20kg%29%289.8%20m%2Fs2%20%29%7D%7B%28%5Cpi%29%5B%28%201.12%5Ctimes%2010%5E%7B-2%7D%29%5E2%20-%20%283.9%5Ctimes%2010%5E%7B-3%7D%20m%29%5E2%5D%20%289.4%5Ctimes%2010%5E9%20N%2Fm2%20%29%7D%5Btex%5D%3C%2Fp%3E%3Cp%3E%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%5Btex%5D%3D%201.80%5Ctimes%2010%5E%7B-4%7D%20m)
(b) Let assume that humerous is compressed by ΔL
Since, strain = ΔL/L0
