A student wanted to create a model to show how sedimentary rocks and fossil fuels are formed. She put a layer of blue sand in a jar. Then she added a layer of white sand, a layer of green sand, and a layer of black sand. What would you tell the student to add to her model to show how fossil fuel would begin to form? Write a note to the student with your suggestions for improving her model.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
