Why are ultrasonic waves partly reflected by body organs?

How sonars works?
The frequencies of the sound waves given off by either a machine or animal bounce off of objects and come back to the animal or machine. As the frequencies travel through the water (or whatever you're using it in) the frequency of the sound waves slow down the further away the object it bounces off of. Therefore, objects that are close to the thing the sound waves came from will come back to it before the sound waves that are further away, making an image. If someone could reword it to make it less confusing, that would be nice. :)
Is sound's a conjunction?
No, it is not a conjunction, but it could be a contraction of the phrase "sound is" (the sound's coming from in back). It can also be the possessive form of the noun sound (the sound's tone changed).

What was the name of the first machine that could be programmed by cards with holes punched holes?
The Jaquard Loom in 1801. Punched cards actually date back to around 1725 when they replaced the perforated paper rolls that were in use at the time, but the machines still required human intervention. It was Joseph Marie Jaquard who improved the technique to create what is arguably the first fully-automated, re-programmable machine; insofar as once it was programmed, the machine could complete the job of its own accord.
