Determine the numerical components (projections) of the forces F1 F2, F3, acting on the profiles of the cube OABCDEGH side a in the Oxyz axis system as shown below: F1=100N F2=200\sqrt{2}N F3=200\sqrt{3}

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.
