No, just a single tube in each.
Yes, it is possible to replace T12 fluorescent tubes with T8 tubes as long as the fixtures are compatible with the T8 tubes. T8 tubes are more energy efficient and have a longer lifespan than T12 tubes.
Modern devices use integrated circuits instead of vacuum tubes because integrated circuits occupy less space than vacuum tubes, are more efficient, consumes less energy and are more reliable than vacuum tubes.
No.
An "amp tube" is more appropriately referred to as a "vacuum tube". It is a very old analog technology that is used on earlier electronic amplification processes. Tubes are generally favored higher than their digital counterparts in the guitar realm due to their tone. Their tone is more lively and complex than the dead, flat sound of a digital amplifier. Generally tubes are wired in a series, each amplifying the signal. The greater the wattage, the more tubes are needed.
Typically, no. Test tubes are generally smaller than beakers and have less volume. Beakers are designed to hold larger amounts of liquid compared to test tubes.
Transistors ran cooler than Vacuum tubes.
yes but vacuum tubes produce more sperm trololol
It depends on the size of the test tube and the flask. Generally, test tubes have a smaller volume capacity compared to flasks. However, there are larger test tubes that can hold more liquid than smaller flasks.
Having your tubes tied is not entirely effective, if you've gotten pregnant once with them tied chances are you can again.
Fluorescent tubes last longer and supply more light per watt of energy consumed than an incandescent bulb.
The cage/tubes setup is more entertaining for both the pet and yourself. The hamster will also get more excersise in the tubes than a tank and will make the hamster feel more at home because the tubes would more represent the natural landscape of the hamsters tunnels in the wild.
The starter tubes are one inch longer than the towing tubes and do not have holes in them
