Question

Answer 1

Explanation:

during a hot day an echo is heard sooner. the speed of sound is high when the temperature is high.

Answer 2

Answer:

On the hotter day.

Explanation:

Well, a day before, i was stuck with the same question. I analysed and got my answer.

Ok . The reason that i answered as hotter day is because that speed of sound depends on the temperature of the medium in which it travels. As the temperature of a medium increases, the particles gain more kinetic energy and can vibrate faster. So the sound waves can travel quickly.

Since the temperature is more on a hotter day, we can hear an echo on hotter days sooner.

Hope it helps.

Thank you. Have a nice day.
