Matt needs a suggestion to test the nature of solution besides it's taste and corrosiveness. what suggestion would you recommend her to identify the acid and alkaline nature of the solution?

A solution with pH less than 7 is acidic while that with a pH greater than 7 is alkaline. So, in order to test the nature of solution( whether acidic or basic) we would use a litmus paper. Litmus paper contains a pH sensitive dye which is red colored in acidic form and blue colored in basic form. Acidic solution turns blue litmus paper red. Alkaline solutions turn red litmus paper blue. Hence, the nature of solution can be detected by using litmus paper test.

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.
