Correct. You can not estimate a digit on digital measuring devices.

Yes, proper scientific notation will be an acceptable format for an answer in the Metric Mastery event.
(section: 4 / paragraph: b / sub-paragraph: i / line: 2)
No, you are correct. On a vernier caliper there would not be an estimated digit.

The entire device (with the cup), in both launch and flying configuration, must fit into a 51 cm cube in any orientation the student chooses. The entire device does not have to rotate in the 51 cm cube when it is being measured it just has to fit within the cube.
Students will be the ones who choose the orientation of their device in the cube and place it in the cube for verification. Students must be the only ones to touch their device. As long as it fits into the allowed dimensions of the cube,in flying configuration which means with the cup attached, then it passes.

The rotor should rotate at least once around a central axis or it could be determined to be a parachute or glider. It will be up to the event supervisor to determine whether the device has rotated around the central axis.
Students will be placed in Tier 3 or 4 if the cup does not hit first. Construction 3.d. "No other shock absorbing or cushioning materials can be used..." If another part of the device hits first it would act as a shock absorbing material.

Yes, this is allowed as long as each part is correctly defined.

The standard English keyboard is identified for use with all Science Olympiad tournaments. However, each tournament may - at their discretion and announcement to competing teams - provide additional or alternate languages that may be used. If the PC standard 101 keyboard is able to make Chinese characters, this would only be acceptable if the event supervisor has identified non-English language may be used. For nationals, English is the identified language. Using keyboard symbols to create non-English words will not be acceptable.

As long as what is written is readily apparent it refers to the "and" symbol and not something else, it would be accepted. Keep in mind that the "+" is not the same as the "and" symbol.
(section: 3 / paragraph: d / line: 1-3)
No, fractions may be referenced as 1/2 or 3/4 etc.
