Since velocity of sound is directly proportional to the square root of its temperature
Then : T1=16+273=289
T2=127+273=400
√289=340
√400=x
Then cross multiply
20*340 /17 = 400m/s

V1/√T1 = V2/√T2
V1=340
T1 =√289=17
V2=?
T2=√400=20
340/17 = V2/20
CROSS MULTIPLY ✖️
340×20=17V2
6800=17V2
V2=6800/17
=400

velocity is directly proportional to the square root of temperature so when the temperature change when a wave is traveling the velocity also change like it change from cold to hot the velocity will increase take note good luck 2026 jambite
