When a baseball player swings a bat slowly as part of their warm up, that is an example of stretching.

Static

Explanation:

The term warm-up in sport is defined as a period of preparatory  exercise to enhance subsequent competition or training performance . A pre-game warm-up for team sports typically  includes a period of sub maximal running, static stretching of the major  muscle groups and sport specific movements incorporating various  range of motion (ROM) exercises with skill-based drills executed at, or  just below game intensity

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

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.
