Homework Statement:: French Fusion Reactor Relevant Equations:: F=ma Hey anyone here working on the French Fusion reactor? Heard about it over the radio. ITER just been reading the annual reports from CERN. Kind of a fun read if you haven’t read it yet.

i fear Earth time may be drifting off by astronomical factors.

whats the deal with February. is the month 28 days or 29 days? every 4 years we have 1 extra day? what the hell. every year should be almost exactly the same length.

they put the furnace next to the internet router. 100%

my apartment has this ancient furnace. it either is electric coil or natural gas. i think its heating oil and pumping it around the building. could it burn natural gas and just pump hot air through the furnace? anyway. its slowing down my WiFi.

i computed 18.71 PSI for the jar of air at 100C its lower than i expected.

The apples were cooked in boiling water. so they probably absorbed a lot of water. that's why i chose water. of course there is lots of other biomass in the applesauce.

No headspace. One Jar broke. but 6 made it!

the constant R doesn't work with a liquid like water. we could calculate the pressure for the air though! that's awesome.

PV=nRT

we could just take the guitar outside and put it on a guitar tuner. it should say the frequency exactly.

I didn't account for F=ma or drag forces.

Nylon 50-90 M/(MxK) what kind of unit is M/(MxK)? the website says: "The calculation is: (given factor) x 10-6 x length x change in temperature °C" but I don't know how to interpret it.

Thermal Expansion equations? steel string or nylon? for most materials they say delta L is directly proportional to delta Temperature. we just need an equation to convert Delta Temp to Tension so a certain tension creates a certain note. thats what you guys were working on right?

I think we just have to consider that the O2 has mass. and the CO2 has mass. and we have to add that in. when its in that giant balloon. we can consider it to be its own object with a certian mass and a certian size (and extremely low mass). so let's just use 1m^3 volume. I think the force from...
