Well yes but I don’t know if that makes it better, cows are just really really fat.
Well the mass of an "Eatin' Cow" is best to not contain a lot of fat, but meat mass. They may be "Very Large" but hopefully it is not much Fat

Ok they are very muscular (and not because they get lots of exercise)Well the mass of an "Eatin' Cow" is best to not contain a lot of fat, but meat mass. They may be "Very Large" but hopefully it is not much Fat

LR44 is a hold-over from a less formalized naming, I assume assigned by manufacturers. There are similar alternate names for many sizes, but only LR44 has really held on.Battery sizes for coin type Lithium.
CR2030 for example. Coin Round. (coin shaped and round)..... Last 2 digits are thickness in 0.1mm increments. Leading digits are diameter in mm.
so Coin Round 20mm dia 3.0mm thick.
SR is Silver chemistry Round. Same but 1.55V usually for watches or old cameras..... SR726 would be 7mm 2.6mm thick silver chemistry.
The LR44 would be an exception...... Commonly used for electronic digital verniers.
So now you just have to buy a LR44, put it in your verniers and measure the battery in your watch with some weird number on it and search on Ebay for SR(Dia)(Thickness to 2 sig digits and multiply X10) if it's a small one or CR if it's a big one Lithium.....Simple....
And the second most abundant element in the universe, helium, is super scarce on Earth for same reason combined with the fact that none of it is bound up in heavier molecules.Hydrogen is the most abundant element in the universe, but not on Earth due to its light weight, which allows the gas to just float off into space.
According to Bing.
True but that’s probably less than 1% of all the beef consumed (and it physically can’t be more than that either) saying 1% of our livestock is happy has some irony.I have had "free range" grass grazing beef, and it's really good.
I hate it when such a wonderful standard is ruined like that!Only three specific isotopes of any element have their own unique names. 3H is called tritium, 2H is called deuterium, and 1H is called protium.
Huh?I hate it when such a wonderful standard is ruined like that!
Most of the time you say the number of neutrons eg He^3 so it’s a standard notation but this time it’s a name and it drives me crazy having to say (and spell) deuterium and the others.Huh?
Super conductive materials placed in a magnetic field exhibit a phenomenon called Quantum Locking.
It basically is suspended in the magnetic field but not necessarily confined to its position in the magnetic field so it can follow a track of magnets.
My all time favorite weird physics phenomenon for sure. It really makes your imagination run wild with ideas lol.Yup super cool, I like to think of it as magnetic drag.
Like the fact that rockets that use fly aways are usually launched from the desert where liquid nitrogen is in short supply…E: Probably wouldn't be the best use for it, but if it were practical... and affordable, imagine using quantum locking to make a no-drag/no-friction rail launch system (not to be confused with a rail gun.. similar parts involved but different concept and goal). Do away with flyaway launch adapters all together. I'm sure this is less this practical in real life, but its just cool to think about
I like to imagine there is a gas station along a random road in the desert that has a fuel pump of L-NO2, complete with the guy in overalls on a rocking chair who judges you for being a "city-slicker" lol
Fun fact about this: its theorized life lived through snowball earth by living in little cavities/bubbles from dark rocks melting into the surface of the ice to create little warmer than freezing microbiomes. (Something I learned from PBS Nova). As he is so famously quoted:At least on one occasion, the entire earth was covered in ice = snowball earth.
You can still say or spell it as hydrogen-2 or 2H if you like.Most of the time you say the number of neutrons eg He^3 so it’s a standard notation but this time it’s a name and it drives me crazy having to say (and spell) deuterium and the others.
Err, no.No it’s neutrons, see just before the diagram, Wikipedia.

Below is the diagram (annotated by me) and here is the caption with that diagram:No it’s neutrons, see just before the diagram, Wikipedia.
The three naturally occurring isotopes of hydrogen. The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of protons and neutrons. From left to right, the isotopes are protium (1H) with zero neutrons, deuterium (2H) with one neutron, and tritium (3H) with two neutrons.
I guess so it’s just that it has always been explained that way even in text books so I don’t feel bad.Below is the diagram (annotated by me) and here is the caption with that diagram:

You are definitely confusing the words "neutron" and "nucleon," and if your textbook is mixing it up as well, you need to bring it up with your science faculty. That is not a trivial error.I guess so it’s just that it has always been explained that way even in text books so I don’t feel bad.
