Fermi Questions C

[PM2017]

Other than memorizing a bunch of facts, is there another way to practice for this event?

Do some practice tests, use http://www.fermiquestions.com/play, work strategy with your partner etc.

Why would you memorize logs for anything other than prime numbers? For all non-primes, just use log rules to figure them out based on the prime logs.

For primes smaller than 10, I memorize all the logs, simply because it's more convenient imo. (Above ten, I might try to memorize some more primes, but only primes)

Does anyone have an idea of what the top national scores would be per question (this obviously depends on the difficulty of the test)?

I know ward Melville averaged a 4.125 pts/question at UPenn I'll probably expect it to be a bit higher then that

While scores like this are possible, they're very uncommon. In my experience, it's very difficult to average more than 70% consistently, and I think 85% is about the most one can go - the reason being variation in sources used to calculate answers.

Although difficulty is a thing, for most top teams expect around 3.25-3.75 individually while paired anywhere from 4-4.5. Of course, there's variation, but far too often top teams are so good that the variation lessens. I would expect top team to be around 4.5 at nationals since most invitationals usually have much more devious tests.

Looking at 2013 nats test it looks relatively easy, and definitely teams could get 4.5ish (I believe the winner averaged 4.69). However I would expect the test to be harder. Also when you say 3.25-3.75 individual are you referring to national level or higher invite level?

Can someone make a quick list of everything physics related I should know for this event? I'm kinda bad at physics.

Also, where do you find the 2013 Nats test?

Thanks!

The nats test was part of a trade I received sry. It is relatively basic with alotta gravity and estimating. Idk physics well (still taking bio :/)
Quick list: gravitational attraction
Gravitational acceleration (basically attraction)
Columbs law
Escape velocity
Kinetic energy
Size of black holes (very niche) it's 2GM/speed of light^2=radius
That's the ones off the top of my head probably alot I'm forgetting
