How can I solve this? I couldnt figure it out so I just requested the answer. But how can I solve this kind of question for the future, in case a similar problem shows up on the test? Specifically Part B of this problem?

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

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.
