An overweight boy and a skinny girl are balanced on a massless seesaw. if they both move forward such that they are one-half their original distance from the pivot point, what will happen to the seesaw?

The seesaw will average out a little bit, and not be as tilted to one side as before.

because if the tool that you are using is not balanced it there would be false mass.

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.
