Two people are separated by 1 m, and the other person's words are considered to take 10 seconds to hear. If the distance is longer, it will take longer, and the communication between people will not be normal. If your classroom is 10 meter long, it takes 100 seconds for the students sitting in the last row to listen to the teacher, which is 1 minute for 40 seconds. People can't live normally. When people make phone calls, the sound they hear will also slow down. The traffic is in chaos. It will be a long time before you hear the thunder after you see the lightning. It may have cleared up, but the thunder is still rumbling, hehe. In short, if the speed of sound is 0. 1m/s, our life will not be today, and the pace of people's life will be greatly affected, which may be abnormal.
1. Hearing the phone, I ran over and hung up; 2. Look at others, you can't see the sound when you see your mouth moving, and it takes a long time to hear the sound; 3. Fighting will stop swearing and start directly; The dog doesn't bark-it's no use barking, it's better to bite directly. 5. You can cover your ears slowly when you see lightning, and you are not afraid of being strangled; 6. Driving makes people shine, and they don't honk. At most, they will signal the light, or poke you with a pole and write a few words on it-sorry, brother. . .
1) The car horn on the road has no effect. Haven't heard the sound, the car has come. 2) 45 minutes is not enough for a class, and the students in the back row dismissed the class without listening to a few words. 3) The starting gun of the competition is useless. The players who are close to each other have already run out, and the players who are far away have not heard the sound. 4) Communication between people can only rely on gestures, which is too slow. 5) Wear headphones or stick your ears on the speaker when watching TV, otherwise the sound and image will be out of sync.
I haven't heard it for a long time. It's been a while since things collided!
