E. The wave travels faster and with an increased wavelength.
Explanation:
As we know speed of the sound depends on the temperature of medium, higher the speed of sound more will be the temperature.
As the sound enters an area of warmer temperature, that molecules of that area posses high kinetic energy hence they vibrate faster resulting an increase in speed of sound. Now more the speed, more will be the wavelength.
Hence when sound wave enters an area of warmer air it will travel with a faster speed and with an increased wavelength.
The appropriate response is letter D. The wave ventures slower and with an expanded wavelength when a sound wave entering a range of hotter air. Hotter air implies less thick, so the wave ought to back off.
I hope the answer will help you, feel free to ask more in brainly.
the rotation of earth is determining what part of the sun faces what part of earth making time the part thats away from the sun would be night and the one facing the sun itself would be day
