Answer: (D) it is not spontaneous.
Answer ; The correct answer is : 346 m/s .
Sound is a type of longitudinal wave , which is produced when a matter compress or refracts .
Speed of sounds depends on factors like medium , density , temperature etc .
Effect of Temperature on speed of sounds :
When the temperature increases , molecules gains energy and they starts vibrating and with higher temperature vibration becomes fast . So the waves of sounds can travel faster due to faster vibrations . Hence , speed of sounds is directly proportional to the temperature or speed of sounds increases with increase in temperature .
The speed of sounds at 0⁰C is 331
The relation between speed of sound and temperature is given as :
Given : Temperature = 25 ⁰ C
Plugging values in formula =>
Because their is no motion in them their for they can not do anything but just sit their I hope I helped u if not I’m so so sorry
Climate changes hope this helps you
