Two balls are rolling towards each other. Ball 1 has a mass of 5.0kg and a velocity of 2m/s. Ball 2 has a mass of 4.0kg and a velocity of 5m/s. What is the kinetic energy of each ball? What is the total kinetic energy?

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
