Answer:
Explanation:
All existing matter and space considered as a whole; the cosmos. The universe is believed to be at least 10 billion light years in diameter and contains a vast number of galaxies; it has been expanding since its creation in the Big Bang about 13 billion years ago.
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

Thus,


<span>B is the correct answer. Neutrons have no charge. In contrast, protons are positively charged and electrons have negative charge. These charges are all relative to each other. The protons and neutrons can be found inside the atom of an element. Electrons float around the outside.</span>
