3. compare how a positively charged object and a negatively charged object interact with a neutral object. i will give 20 points to whoever asks first and a medal.

They are not interacting to each other in both cases.
Connect electrical wire to rubber mat. Nothing happens.

However, in some cases when both objects are for example metals this happens:
1) positive - neutral case
if you connect positively charged (object P, experiencing short of electrons) to neutral object (object N), after some time they both will become positive. This means that object P would gain some missing electrons from the object N. The object P becomes a bit less positively charged than before. The object N becomes from neutral to positively charged as it loses some of it's electrons.

2) same story with negatively charged and neutral object.
If you connect them, after some period of time negatively charged (object A) will exchange electrons with neutral object B. After some period of time they both will become negatively charged. Object A a bit less negatively charged compare to initial stage
 

For me a person with a phd and who knows what there talking about.i know the chances of a radiation leak is low but if it does the area within a 96.3 mile radius would be unusable because of contamination

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
