Have you tried the unit conversions? There's a little unit button on there, but it's a little difficult to figure it out. Here's a little tutorial batesville.k12.in.us/Physics/CalcNet/Calculator/ti_89/units_conversion.htm

But, if you use a steam engine there will be a greater removal of heat from the engine, possibly eliminating the radiator and the radiator fan.

search "crower engine" pretty cool

My guess, and it's only a guess. But, yes the forces are incredible with pistons, but the mass is relatively small. When you make that mass (the piston mass that is) smaller or larger, the counter weight will not be optimally positioned to get the most "bounce back" force out of the spin it...

Alright then, what do magnets follow? And wouldn't friction be something that would be dealt with later? As I would find a force on the graph that would equal the normal force of the magnet? Does anyone know an answer to this question, it is driving me nuts. (How to find the force between two...

Okay, I have an equation. If you're going through air between the magnets, the equation will be F=Magnetic Permability constant*S1*S2/r2 That is, (4*pi)×10−7 N·A−2 times the strength of the pole of interest number one times the strength of the pole of interest number two divided by...

No, I did not. I'm hoping my AP Physics teacher might have an answer, he is usually so busy, but now after the test he might be free.

okay, let's rephrase. So I have two permanent magnets, one is pulling 30 lbs and the other is pulling 20 lbs. There's a .5 coefficient of friction, and they're opposite poles. How would I figure out the distance at which the magnets would overcome the coefficient of friction and pull each other...

No I'm not, I will be studying to be a physicist or biomedical engineer next year though (going into college next year). And I'm still not getting this threshold of attraction, have any links?

circular magnets, 2" diameter (both of them) and air is in between them, and what is the threshold of attraction?

Hmm, well a little late, I know. But Rocky, since you're in geometry I assume you've been in Algebra I. In Algebra, you learn about rise over run, you count up how many boxes a line goes and how many boxes over, it goes, divide the up by the over and you've got your slope. This is great for...

I have a question for the enlightened minds. In physics class we found our debrouille (sp?) wavelength, we found that an average human gives a ridiculously small wavelength. H/p. Now what happens when you do this to an electric current in an exposed wire? (6.626E(-34) m2 kg /...

The problem with getting hydrogen from water is that the energy required to separate the two would be the same (assuming 100% efficiency) as the energy released when they are joined. It doesn't create energy, it allows for storage of it, which is what a fuel cell does, but when you are putting...

Although no one will like this idea as everyone loves a good steak, but get rid of the cattle industry. Insects, although a large annoyance, are extremely easy to culture (leave some sugar out in the summer), they reproduce like nobody's business, and they are inexpensive (compared to cattle)...

Hello, Let's say I have a neodymium magnet with 20 lbs of force, and an electromagnet with 200 lbs of force. Is there a way I could figure out the maximum distance that they would attract each other?
