Number one was that it traveled 50 times faster than the speed of sound.

第一题它行进的速度比声速50倍。

Ten-second trivia: While not constant, the speed of sound is typically how fast?

虽然声速定的，但通常有？

In the strong cough, that air can travel at speeds close to the speed of sound.

It traveled blank times faster than the speed of sound.

它传播的速度比声速倍。

He said a Russian aircraft had launched the hypersonic missile from Russian airspace into Ukraine.

他说，一架俄罗斯飞机从俄罗斯领空向乌克兰发射了这枚高超声速导弹。

Here comes the boom, a supersonic object is traveling faster than the speed of sound.

轰隆隆的响声传来，一个超音速物体正在以高于声速的速度在空中飞行。

We see here, it travelled blank times faster than the speed of sound.

我们在这里看到，它行进的速度比声速倍。

So I see times faster than the speed of sound.

所以我看到了比声速倍。

But already I see here the speed of sound, which is what we have in the table here.

但我已经在这里看到了声速，这我们在表格里看到的。

Still, mach I or the speed of sound is not something that`s reached by passenger planes, at least not anymore.

仍然，马赫一号或声速客机所达到的，至再如此。

Air temperature changes this, but the sound barrier can typically be broken at around 760 miles per hour.

We're looking at faster than the speed of sound, Earth's surface.

我们看到了比声速，地球表面。

Because the speed of sound is much greater in Helium than it is in ordinary gases.

因为氦气中的声速比普通气体中的声速大得。

That's why the speed of sound -- which is a wave -- doesn't depend on the sound itself.

所以声速——也就 Wave - 依赖于声音本身。

So it says, it crashed through the upper atmosphere at around 19 kilometers a second, above 50 times the speed of sound.

所以它说，它以每秒约19公里的速度坠落通过高空大气层，比声速50倍。
