If the potential due to a point charge is 500 v at a distance of 15.0 m, what are the sign and magnitude of the charge?

Explanation:

The potential V due to a charge q,  at a distance r, is:

k=8.99×109 N·m^2/C^2      :Coulomb constant

We replace the values in order to find q:

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
