Answer 20

#7 same deal

Answer 21

#5 swimming pool?

Answer 22

#8, whenever you have electricity you will have magnetism.around it.

Since the question said "electromagnet", you know that it's not an electric field, so what's the other one? That's your answer

Answer 23

ok.., so for #5, swimming pool has lots of water right?

And while pure water is non-conductive, water which has lots of thing in it like minerals and such are not, so swimming pool is not the right answer

Answer 35

how is neutron 60?

Answer 36

what's the mass of the atom?

Answer 37

mass = atomic number - neutron
u know mass and atomic # already, u can solve for neutrons

Answer 38

and @HelpingHawk, please explain next time if you give out answers. It's not really helping anybody with just the answer :P

Answer 39

108 nucleons - no. of protons47= 61 neutrons
