A) What magnitude point charge creates a 12596.37 N/C electric
held at a distance of 0.593 m?

Explanation:

Given

Required

Determine the magnitude point charge (Q)

This question will be solved using of the electric field formula

Where

Make Q the subject in

Substitute values for E, r and k

Express in standard form

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

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.
