Substance a and b are colorless, odorless liquids that are nonconductors and flammable. the density of substance a is 0.97 g/ml; the density of substance b is 0.89 g/ml. are a and b the same substance? explain your answer.

A and B are not the same substances.

The reason is because they do not have the same density which is a function of their masses and volumes.

For instance, for every Volume of 1mL of each substances, A has a mass of 0.97g which is different from the 0.89g of B.

answer: h+ its less than oh

explanation:

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.
