Which of the following objects would require the use of a small-scale model? a. an atom. b. the planet saturn. c. the highway system in florida. d. the path of an ocean current.

Hey there!!

I believe the answer is A) Atoms. I think that because if scientists or some very important people wanted to come together to explain a situation about the atom, they could have a small model to show what they need to dicuss so it can explain it for them so they don't have to explain it in a whole paper report or something like that.

Hope this helps!!!

Happy Holidays!!

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

the answer to this is proletariats.

hope this : )
