Create a series of eight successive displacements that would program a robot to move in an octagon path that is as close as you can get to approximating a circle. The robot should returns to its starting point after the eighth displacement. What total distance does the robot move? Calculate the radius of the circle that has this distance as its circumference.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch

360seconds i 1 hr

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.
