New question: what is price of single item in the displays at the NYC Apple Store converted to japanese yen?

Not entirely sure what you meant here, but here's my guess:

My guess is the new iPhone is what is currently in the displays at the apple store, price = \$800 = 8e2. If I remember correctly, the yen floats around e2 yen to the dollar, so that takes the price in yen to 8e4, which rounds to fermi answer of 5.

Next Question: How many carbon atoms are in the average american?

Attempt

The Tsar Bomba was a thermonuclear test with a warhead yielding a total energy output equivalent to 50 megatons of TNT (already this is more information than I should be giving you, but I think this might be obscure). Using this information, calculate the number of simultaneous detonations needed to equal the energy output of the Sun throughout its lifetime.

Question: If you stack every single order of playing cards(unique shuffling of a standard 52 card deck) on top of each other, how many times can you go from earth to the sun?

Cards

Real thing

If every student only ate cookies for the rest of their student career as replacement for their daily meals(in terms of Caloric intake), how many hours of jump pullups amongst every student would they need to burn 60% of their total cookie consumption?

If you allowed an entire grocery store's stock of 12-oz coke to go flat, what is the volume the carbon dioxide would occupy in one atmosphere?

gonna completely guess, but, let’s say each bottle has E-1 m^3 of CO2. Assuming the store has about E2 packs of 36 each, there should be E1 m^3

Solution:
apparently each can has about E-3 of CO2...

New question: how many base pairs of DNA are there in a human?

If the entire population of the earth was converted to energy and used to power a MacBook Air, how far would the chain of all the electrons that pass through the MacBook in that time stretch in light seconds?

I will assume that this is via the energy-mass equivalence.

Attempt

You drop a golf ball from the top of the Empire State Building - when it hits the (perfectly elastic) ground, it causes a vibration. How many golf balls would have to simultaneously hit the ground at the same point to produce a seismic wave as powerful as the 1906 San Francisco earthquake?

Because of thanksgiving:

How many Joules of turkey energy are consumed by Americans on thanksgiving?

Also, how many (completely empty) Empire State buildings could you fill with those turkeys?

I'll ask a new question: How many cubic meters of sweat does Valery Gergiev extrude while conducting Stravinsky's Firebird?

### Re: Fermi Questions C

Ha! A funny question! I do not know if the man made many recordings of Firebird, but I'll choose the famous one, since the others are probably the same!

Ok! Here we go!

ok so, Firebird is about 45 minutes long if my memory serves me correct, not including audience claps.
Now Valery does quite a bit of working out, haha, and we might equate it to a normal workout...! In fact, we shall do so!
I do not know how much I sweat when I work out, but I do know how much water I usually drink! About half a litre, I think. And maybe I sweat as much.
Now we must examine, if Valery is really doing so much of a workout! I think not. Perhaps.
However, we must look that he is conducting in a hot suit, and waving a stick around for 45 minutes! Perhaps this makes you sweat a lot!
Furthermore, he has much energy! I remember that he does sweat a lot even at the beginning, before the finale, et cetera...so I would have to go with 1 litre, which comes out to be -3, I think.

What the actual answer is, I do not think we shall ever know! But we can look at the actual numbers, and it says you sweat around a liter every hour when you exercise! So I think I may be right.

Fun problem I have for you! So fun, I make into a poem. Or a song, you can sing if you want
I went to tower of Hanoi one day,
and there I saw them stacking rings!
In my head maths began to play,
And I wondered how many ways to stack those things.
How many rings, I don't know, but let us say there were 88.
On three stands, were these rings,
Each stacked on another with a radius more great.
All at first were on one stand,
A move is to take the top ring of a stand and put it on another stand, fun!
But the catch here really is quite grand!
You cannot put it on a smaller one.
So I sat there and I ask to me,
If all start on one stand and we make only legal move,
At any time, how many legal positions can there be?
If solve this you can, a Fermi master you will prove!
hoping to enjoy another year of the science olympiad!!

Hmmm 1 ring 3 combination 2 ring is 9 and 3 is 27 I think which means equation is 3^n. Log(3 is .477 times 88 is 42

Question: what is the gravitational acceleration In m/s^2 of 2 identical balls weighing the mass of the sun separated by the plancks length

Question 2: If the balls both gained 1 electron how many newtons of force would the balls initially experience

### Re: Fermi Questions C

Been well over two weeks, will try to start this again:
if you took every blood vessel in your body and laid it end to end, how many times could that length (ignoring the width!) wrap around a neutron?
