(HW 2.2 Problem 15.10 What is the history graph for this wave at z 0 mfor t 0 sto8 s? l Review| Cons tants I Periodic Table Figure 1) is a snapshot graph of a wave at t 2s y (cm) Tt (s) Figure 1 of 1 y(cm) t (s) y (cm) 1 m/s y (cm) X (m) -1へ1 23 4 5 6 7 r (s)

Answer 1

$From\,\,the\,\,given\,\,figure\,\,1\,\,\\ at\,\,t=2\,s\,\,and\,\,x=0,\,\,\,\,y=0\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, \,\,\,\,\,\,[Origin\,\,point]$

$Now\,\,in\,\,the\,\,provided\,\options\,\,x\,\,is\,\,always\,\,0\,\,\\then \,\,\,\,y\,\,must\,\,be\,\,0\,\,at\,\,t=2\,s\,\,\,\,\,\,\\ Only\,\,3rd\,\,option\,\,satisfies\,\,this\,\,condition.$

$\dpi{120} \boldsymbol{\therefore 3rd\,\,option\,\,is\,\,correct}$
