#5. The electricity that comes from a power point is AC, but what does that stand for?

Alternating current electricity keeps reversing the direction that the current flows.

#6. What element is coal mostly made of?

Coal is mostly made of carbon, which is why it produces carbon dioxide when it is burnt.

#7. What’s the name of the line running across Australia that separates the tropics from the temperate zone?

#9. Which of the following is about 1.34 parsecs?

Astronomers use parsecs to measure distances between stars. The distance to Alpha Centauri is 1.34 parsecs, or about 40 trillion kilometres.

#10. If you wanted to make a guitar string one octave lower, without making it thicker or looser, how much longer would it need to be?

To make a note one octave lower, the string needs to vibrate at half the frequency. To do that, it needs to be twice as long. In real life, bass guitars are usually a bit longer than guitars, but the strings also tend to be thicker and looser to reach those low notes!
