The nucleus of an atom can have either a positive or negative charge. select the best answer from the choices provided t f

FALSE

Explanation:

Nucleus of an atom consist of neutrons and protons and it is the smallest part of atom.

So the total charge on the nucleus is due to charge of protons as we know that neutrons are neutral in nature and they do not have any charge on it.

So we will have

so here we can say that total charge on a nucleus must be positive charge which is only due to protons present inside the nucleus.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
