What is the definition of velocity? (AKS 1/DOK1) • A. a measure of how fast something is moving in one
O B. always calculated as a unit of displacement divided
O C. all answers are correct
O D. the displacement covered per unit time

c. all answers are correct

Explanation:

Im taking the test now

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

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.
