To test if mechanical waves work in a vacuum, you would need to conduct an experiment where you create mechanical waves in a controlled environment that is a vacuum. If the waves can still propagate and be detected in the vacuum, then it shows that mechanical waves can work in a vacuum. If the waves cannot propagate or be detected in the vacuum, then it indicates that mechanical waves do not work in a vacuum.
Mechanical waves can't pass through a vacuum. Mechanical waves need something to pass through. Space is generally considered a vacuum, with nothing in it to transmit a mechanical wave.
To test if mechanical waves work in a vacuum, you can conduct an experiment by creating a vacuum chamber and placing a source of mechanical waves, such as a vibrating object, inside. Then, observe if the waves can propagate through the vacuum and be detected by a receiver on the other side of the chamber. If the waves can travel through the vacuum and be detected, it indicates that mechanical waves can indeed work in a vacuum.
In 1946two Americans, Presper Eckert, and John Mauchly built the ENIAC electronic computer which used vacuum tubes instead of the mechanical switches of the Mark I. The ENIAC used thousands of vacuum tubes, which took up a lot of space and gave off a great deal of heat just like light bulbs do. The ENIAC led to other vacuum tube type computers like the EDVAC (Electronic Discrete Variable Automatic Computer) and the UNIVAC I (UNIVersal Automatic Computer).
no
You are asking two separate questions. The transmission has a cable,mechanical, kickdown. The distributor does not have a vacuum advance.
No, he had to use mechanical gears, etc. because they were the only device technology available in his time. Electric relays were first developed about 15 years after he designed his computer, while vacuum tubes were first developed about 90 years after he designed his computer.
No. Light is an example of an electromagnetic wave, which can travel through a vacuum. Mechanical waves must travel through a medium, and cannot travel through a vacuum.
