So it takes less energy to take the same amount of fluid out of the smaller tube?

Is the adhesive force greater in a smaller tube then a bigger tube at the top? So would it take more energy to take out water at the top of the straw from the thinner straw? Or would, due to gravity cancelling eventually the capillary rising, the adhesive force at the very top of the straw is...

Thanks for the reply, Yes it is +- 1cm, in my setup the magnet doesn't touch the metal, the magnet is attached to an arm and the metal it attracts is +- 3cm away from the magnet holding it just in place against an plastic wall. When i move the magnet 1cm away from from the metal the metal drops...

I think i used Newton-meter for the equation, 10 gram is +- 0.001 Newton meter. But is this not correct to measure the force to separate the magnets then? How else would be a correct way to calculate it? And if Newton meters per second is correct shouldn't i need to divide 0.001 by 100 since i...

Hi, i have a question. I need to know how much Newton it takes to separate 2 magnets or a magnet from a from a piece of metal. I've bought a spring scale that measures max 50 gram, so very accurate. Now what if i attach the scale to the magnet and i pull it horizontally just enough to...
