Finally, consider the gravitational force generated by a spherically symmetrical massive object. the magnitude and direction of such a force are given by newton's law of gravity:
, where ds =drr^; g, m₁, and m₂ are constants; and r> 0.
find .
express your answer in terms of g, m₁, m₂, r₀, and .

an energy transformation flow diagram is shown

where is it ?

i think its c if i'm wrong

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.
