1. वायु में ध्वनि का चाल 332 मीटर/सेकण्ड है। यदि लम्बाई का मात्रक किमी तथा समय का मात्रक घण्टा हा तब चाल
का मान क्या होगा?
उत्तर. 1195 किमी/घण्टा।​

Answer 1

Answer:

since, speed of sound in 1 second = 332m

thus, speed of sound in 3600 seconds (1hr) = 332×3600

= 1195200m

19920m = 1195200/1000

= 1195.200 km

So speed of sound in air. = 1195.200 km/hr

Answer 2

Explanation:

Speed of Sound in 1 second = 332m

Thus, the speed of sound is 3600 seconds.

(1hours) = 332×3600

= 1195200m

19920m = 1195200/1000

= 1195.200 Kilometres

so, Speed of Sound in air = 1195.200km/hr
