can u please explain what is mean by ''k'' in equation i know that is constant but what does it really means.

[derekowens]

@MsTightman k is one of the constants of the universe. It is basically a number that tells us how strong the electrostatic force is. Just like G is a constant for the gravitational equation, k is a constant for the electrical forces.

Why are electrons referred to as elementary particles if they themselves are made up of quarks?

[derekowens]

@JesusWasADerelict Because we can never break an electron apart into its constituent quarks.

This is really going to be beneficial for my quiz later tonight! Thanks

[hyphysimon]

this is great dude. it helps

@JesusWasADerelict electrons are not made of quarks. Protons and neutrons are.

wtf why didnt my teacher tell me this shit lol

[ChickCalculus]

Are there really students learning about electromagnetics that haven't taken alegebra 2? Ahh, I'm just learning this stuff and I'm my second year of AP Calc BC.

[MsTightman]

@derekowens u rock i am extremely thankful!

[MsTightman]

welldone!sir

@JesusWasADerelict Hadrons are made from quarks. Electrons are Leptons, not Hadrons -- they haven't been shown to be composites of anything else.

[backyardbeachbum]

you are better than any math/physics teacher i've ever had. i appreciate this soooo much.

[JesusWasADerelict]

@derekowens Alright gotcha, cheers
