Thanks.

Forgot about quarks, but I haven't studied them at all. Ok I think follow. Thanks. A follow on question... if you have 2 protons, then it's quite trivial to calculate. What if I have 2 clumps of protons. Are the charges simply additive? 3D interactions seem much more complex than individual...

Coulomb's law states that the force between particles depends on their charge. But protons and electrons have equal but opposite charges. Shouldn't the formula simply have constants with the only changes required being the signs?

Just wikipedia https://en.wikipedia.org/wiki/Magnetic_reluctance. Basically I realized that magnetic flux depends on the medium that it's present in. Air isn't very good at 'conducting' flux, iron is. There was another picture of an atomic sheep floating around the internet, but I can't find it...

Why does an iron core increase magnetism? Apologies if this more advanced than high school. EDIT: Disregard, found article on magnetic reluctance.

I'm more trying to understand why the pressure under each wheel is a quarter of the whole car? This to me doesn't seem intuitive/obvious. I only brought the ice example because it's a classic way of talking about the problem. I don't understand why the car can't weigh a tonne and the contact...

If we have a car with no wheels an one of those sporty aero flat underside sitting on ice, then the pressure is just equally distributed throughout the whole underside and is relatively low, so a thin layer of ice can support it. What happens when we put the car on wheels? The contact patch now...

Well if you have 5 apples and another 5 apples and you multiply them, then you have 10 apples + 15 magically created apples :), I'm not trolling I promise. So what do you get when you multiply apples by apples or force by force... good question... no idea. I guess what kuruman said... We...

Reading about this... very interesting. Exactly the info that I was looking for. If you're counting apples... 2 apples per bag x 1 bag... = 2 apples or 1 bag. How can you multiply a bag by an apple? You've got abstract things like bags apples force displacement. Then if you multiply 2 apples...

Wikipedia says: The work done by a constant force of magnitude F on a point that moves a displacement (not distance) s in the direction of the force is the product {\displaystyle W=Fs}[PLAIN]https://wikimedia.org/api/rest_v1/media/math/render/svg/b020230128c115d1b9e9cfbe6636985e98bbaf69. The...

Stress -- Cross-sectional and Inclined planes As per attachment... "On the cross-sectional plane mm the uniform stress is given by P/A, while on the inclined plane mm the stress is of magnitude P/A'. In both cases the stresses are parallel to the direction of P." The parallel part...

Basically in a sound editing program, there's an option to view the Fourier transform over a period of time... if you view this Fourier transform at any given time, it's as Simon Bridge pointed out, a bunch of spikes that correspond with the individual periodic components, however since we're...

If a basic sin sound wave is analysed with a Fourier transform, the result is just a spike at a certain frequency. My maths isn't the best so bare with me... if we take a real sound file and take Fourier transforms at regular intervals (I assume that's what's being done when calculating a...

By uniform expansion of gases, I was trying to state that I was trying to work in an environment where combustion pressure was uniform from the top of the stroke to the bottom (so working in a prefect world scenario). So I am trying to figure out whether the vector force component pointing...

Assuming you have a uniform expansion of gasses upon their ignition from the top most piston position to the bottom, would the force generated on the crankshaft vary at different points in the down cycle? My logic tells me that when you are in the top most part of the cycle, you would have a...
