How far apart are the planets?
The distance between planets varies greatly depending on their positions in their orbits. On average, the farthest planets (Neptune and Uranus) are around 19 AU apart, while inner planets like Earth and Venus are only a few AU away from each other. The closest distances occur during planetary alignments, where some planets can be less than one AU apart.
How does the transistor circuit differ from the thyristor circuit?
A thyristor is a "triggered" device. It will remain off until its gate electrode is made to conduct. It will then stay on (showing a very low resistance) until the power is removed, or (in Gate Turn Off devices) until a turnoff voltage is applied. A transistor can be used as a variable-resitance element. While it can be made to switch (like a thyristor) it does not need any special turn-off: just remove the input signal and it will go open circuit. A transistor can be made to respond to a vaying input signal with a varying resistance, so it can be used as a linear (analogue) amplifier.
What shapes of pasta is there?
There are over 400 different pasta shapes ranging from Long pasta much like spaghetti and vaying from there to be thinner or thicker or hollow or ridged. Then there are short cut pastas like Ziti or Rigatoni. These are also, hollow, solid, ridged, flat surface and some that are even completely flat. Stuffed pasta shapes such as ravioli and tortellini. Soup pastas or pastina such as alphabets, stars and orzo which is pasta shaped like rice. The list goes on and on and you could literally eat pasta every day for a year and not have the same pasta shape twice.
