Question

एक मजबूत ठोस ईंट की दीवार के पास एक व्यक्ति
धात्विक घण्टी को बजाता है। वह 0.3 सेकण्ड में
इसकी गूंज कितने सेमी दूर सुन सकता है?

Answer 1

Step-by-step explanation:

Echo heard by him =0.3s

Time taken for sound to go there =0.3/2=0.15

Velocity of sound=340m/s

Distance from the person to the wall =time taken for sound to go there*speed or velocity of sound

=340*0.15=51m

Distance from the person to the wall=51m
