Helppp!! The diagram below shows a simple motor. The loop of wire is attached to the split-ring commutator.
a. Does the current flow through the wire from A-B or from B-A?
b. The current running through the loop will cause it to spin. Will this cause point A
to move up or down? How do you know?
c. What is the purpose of the split-ring commutator and why must it be used on the
motor for it to work properly?

this could be newton#'s law of cooling. the cooling curve is exponential

i believe the answer is electric potential.

explanation:

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.
