The gravitational force between two objects is 2000 n. the mass of each object is reduced to one-third of its original mass.
how must the distance between the objects change to keep the gravitational force between them 2000 n?

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.
