Answered by artikp

put the speed formula distance/time
12/4
3

ManpreetStar1: why??

artikp: because time 4 is given in question

ManpreetStar1: but it's for going backward and forward

ManpreetStar1: not time period

artikp: why we put it backward and forward

artikp: I put the speed formula

artikp: sorry

artikp: yes right

ManpreetStar1: kk thnx

artikp: its my pleasure

Here it is physics

Now look here the string length = 12 m
Or you can say the distance = 12m * 2 = 24m

Now the time is given = 4 seconds

Therefore the
Speed of the pulse = distance /time
= 24/4 = 6

Therefore the speed of the pulse is 6m/s

ManpreetStar1: it's given for forward and backward time is 4s

ManpreetStar1: r u sure i m right

ManpreetStar1: bcse it came in my exam

ManpreetStar1: ohk

ManpreetStar1: i had marked it brainliest

ManpreetStar1: thnx bro
