Read the excerpt from "Black Hole Beginnings."

As the nuclei meld, a smidgen of their matter vaporizes into energy. This creates a tremendous burst of furious noise, motion, and another by-product: star shine!

Which statement correctly defines the cause-and-effect relationship described in this excerpt?
Star shine is an effect of matter vaporizing into energy. Once the nuclear reactions stop, (the star's center begins to cool.)One cause (star material gathers) leads to one effect (inward pressure grows), which becomes a cause of two additional effects (nuclei zip and zoom, and nuclei veer away from each other).

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

c. magnitude and direction

force tends to be low and long diustance masses are high

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.
