You could probably calculate a reasonable specific heat from the information here (thickness of the steel pipe is important, also). Just add up every component you know: (total mass of steel)*(specific heat of steel) + (total mass of dry soil)*(specific heat of dry soil) + (total mass of...

No, I don't believe that is right. I did the calculation 2 different ways, and got 1 kV/cm = 1.945⋅10-7 a.u. both ways. 1st method: dimensional analysis. I believe the atomic unit for electric field is Eh/(e⋅ao), or Hartree per fundamental charge per Bohr radius. 1 kV/cm * 1000 V/kV * 100 cm/m...

I don't see anything wrong. The reduced equation in c) is exactly the normal production of lead(II) iodide from ions, so it is a good thing to reduce to.

You lose some accuracy if you use complex numbers, but one easy way is to do ln(e^(5 ln x + 6 ln y - 4 ln z)). Use diamond-x for e^, or CHAR-MATH-5 also gives you the correct e. This is just a simple algebra trick: ln(e^x)) = x, but the calculator doesn't try to simplify anymore. If you do...

I had the same problem, and similarly could not find an answer online. But here it is: Assuming you are using Matlab, you do not need the parentheses when you call the function. You defined it correctly (although you shouldn't need brackets): function sumout = sortabc(); When you call a...
