Which of the following statements is true? a. matter requires energy to move and change. b. energy cannot change from one type to another. c. energy must remain where it is created. d. it is not possible to store energy for later use.

A.True.  Matter requires energy to move and change.

B.False.  Energy CAN change from one type to another.  (Like changing the chemical energy in gasoline to kinetic energy of a moving car.)

C.False.  Energy need not remain where it is created.  (Like generating it in an electric power station and shipping it to your house to run your hair dryer.)

D.False.  It IS possible to store energy for later use.  (Like in a battery.)

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
