You can measure the internal resistance by shorting the battery through an ammeter and measuring the terminal voltage.
I think I'll go short the battery in my car and measure the resistance with my Fluke. Anyone want to tell me how long I have to make the measurement before the battery explodes?
I would guess 15-25 seconds, depending on the device used to bridge the gap. If I laid a nice big wrench across it, I bet it would work nicely.
I'm not sure if the initial sparks would cause a reflex reaction, so I'll do it blind-folded.
Terminal voltage when shorted, divided by current through the ammeter, gives internal resistance.
Now, take the square of the charging current and multiply by the internal resistance. This gives the heat dissipation in watts.
The fun part will be seeing if I can do the math before the battery explodes!

I would have to wonder if your parents actually listen to what you have told them about modern computing...
My parents have listened to what I've told them regarding their computers, and they've only had one virus and no adware/spyware since I turned them loose on in the spring of '94. Mind you, they had no previous experience with computers and don't really use them much in their careers.
Those of you whose parents are constantly fighting virii and malicious apps, despite your repeated warnings, I would suggesting looking for the root of the problem in your relationship with your parents. They probably aren't listening to what you say because they don't respect what you have to say.
That's the influence that 18 years of you lying to your parents had on them.
...is that you thought to yourself "that's sexy, I'm gonna whack off to this" while I thought "I bet he has a prolapsed rectum and cannot walk without shitting in his pants."
yes, I do like responding to my precious little trolls. bite me.
...but I do not plan to give them unlimited access (or unlimited time to spend at a computer) at such an early age. I was not raised by a television and I sincerely hope that I can match my parents' succesess by not allowing my own children to be raised by a computer.
[given two things: 1. they are still available 2. i actually end up with kids one day]
I spent a lot of time when I was 6-12 years old reading my parents encyclopedia's and old college textbooks from cover to cover. I can still recall a lot of things (over 20 years later) that I read when I was a kid that have stuck with me, without further exposure or reinforcement.
Actually, scratch #1 up there, if they aren't available, I'll find an antique set for them.

I once had a log ("sharks" as a chinese ramper called them, with the greatest accent 'shawks!') that hit my arm on the way out. I had a nice big chunk stuck in my watch band.
I have seen at least 2 people take some bad stuff (cargo DC8 and a DL767) directly to the face/mouth.
But me thinks the whole song really wasn't about the film...
But alas, Kodachrome is no longer the same formula/look/saturation that he wrote about, and 25 isn't even made anymore. Now we only have 64.
Velvia (50) is my 35mm slide of choice. I think it was written that it would take an 18 megapixel camera to duplicate the small grain size (resolution) of velvia 35mm slides. MF was around a ~30 megapixel equivalent and LF was ~80 megpixels iirc. Not to mention that there are other things besides resolution to consider. It would require much more advanced CCD's in terms of color precision/accuracy
if you wonder how water manages to get airborne, remember the molecular weights of the above molecules.
Water (molecules) is (are) lighter than air.
It's just that those molecular bonds make water molecules lock in pretty tight together, increasing their density until they begin to fall. But even then, strong updrafts can throw those drops up to 40,000 feet or more to make hail.
The failsafes in the grid are to protect the hardware, not to keep the power on.
As for the duration of the blackout, generation has to match the load. It's very difficult to start everything back up when so many generators have to spool up to match umpteen sections of the grid....
The difference is that we could accurately model the flight envelope for the shuttle at its inception, but could not for the X-15.
I respectfully do not agree with "the point"
The X-15 and related programs were the research necessary for the shuttle.
Although the shuttle also did not meet its initial design expecttations, it has obviously had great value beyond proving concepts or recording flight data
Note that "prototype" airliners now join the fleet soon after the launch customer receives the first production aircraft.

Are you sure you aren't thinking of the Nyquist frequency?
It has to do with the threshold of digital sampling rates.
