The overall charge of the nucleus is a. positive b. negative c. neutral

The overall charge of the nucleus is POSITIVE. This is because the nucleus of an atom is made up of protons and neutrons. Protons are positively charged particles while neutrons are neutrally charged particles which means it has no charge and cannot effect the protons electric charge in any way. Therefore, since the only effective charge is positive, we can conclude that the nucleus is also positive.

Let me know if you need anything else. :)

Sorry can’t u just tryna get points

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
