I took physics at secondary school without giving much thought to the relevance of it all. But there are ordinary daily situations in which we use physics without even thinking about it. For instance, it seems “logical” that you need a jack to raise a car, so that a tyre can be changed. This week’s quiz consists of fairly clear situations, and questions about how science applies. It is also multiple choice (and therefore brute-forceable if you must).
Wow. Just wow.

Are you sure about Q1? I think it is the other war around. Actually it depends. There is missing an information we can say for sure although we can assume.

Yes, I'm pretty sure by the principle of Archimedes.

If I understand that Wikipedia article correctly we have to assume that the canonball does not sink into water because otherwise the principle of Archimedes will not work.

The cannonball is sitting on the boat, displacing some water (by the principle of Archimedes). Then we throw the cannonball overboard into the water, where it will most likely sink, as cannonballs tend to weigh a fair bit. Once in the water it will also displace some water. The question asks you to contrast the displacements.

I understand that and I have the puzzle completed. I just come to another result as you.

And you are completely correct, and I am wrong. Q1 is being fixed. One hundred apologies.

There is no need to apologize. I was just irritated since I got the very same question from another physics studying friend some time ago (he used a coin instead of a canonball) and it was unlikely that both of you could be right with different results.

With a coin, you potentially get a different answer. Contact me on Steam and I will explain.

Importantly, this went up without my getting the final giveaway code from Jeff, so could the first four solvers: Faragona, Citrinate, Adelion, and Svipur, please open it again to progress in the larger puzzle.

Hey!! I remember how much fun it was having you in the Science event as a puzzle creator... here's a chance at another event I'm doing-- hope you can return with designing a puzzle!!
