1.a.A girl stands 160m away from a high wall and claps her hands at a steady rate so that each clap coincides with the echo of the one before .If she makes 60 claps in 1 minute,what value does this give for the speed of sound?
b.If she moves 40m closer to the wall she finds the clapping rate has to be 80 per minute.What value do these measurements give for the speed of sound?
c.If she moves again and finds the clapping rate becomes 30 per minute,how far is she from the wall if the speed of sound is the value you found in
2.a.The distance between two consecutive rarefactions in a sound wave is 2.5m.The speed of sound in air is 330m/s.Calculate the frequency of this sound wave.
b.A person makes a loud sound and hears the echo of this sound 1.2s later.Calculate how far the person is from the object causing the echo.Assume that the speed of sound is 330m/s.
看在我那么辛苦的把它打在这个上面，

楼上的不能这样忽悠啊.要不就别翻.
唉,做回好人吧.
1.
a．一个女孩站离一堵高墙一百六十米远的距离上,以一个稳定的速率拍手,每次拍手恰巧和前面一次拍手重合.如果她每分钟拍60次手,这时的音速是多少?
b 她向高墙走近了40米,鼓掌频率变成每分钟八十次,这种变化对于音速意味着什么?
c 她再次移动,拍手频率变为每分钟30次,如果音速值是你根据a算出的,她离墙多远?
2.
a.在声波中连续两个稀疏之间的距离是2.5m.音速在空气中按330米/秒算,计算这个声音的频率.
b 一个人大声喊话,1.2秒后听到这个声音的回音.计算这个人距离产生回音物体有多远.假设音速是三百三十米/秒.

1.aA女孩站在一百六十○米远离高的围墙和claps她的双手在一个稳定的速率，以使每个拍手恰逢回声面前的一个。如果她60 claps中，以1分的价值，这让为音速？
她动作b.If接近40米的墙，她认为，鼓掌率是百分之八十的价值minute.What这些测量给予用于音速？
她动作c.If再次认定，成为拍手率为每分钟30日，在多大程度上是，她从墙上如果音速的价值是你发现的？
