The concentration of yeast t-RNA in an aqueous solution is found to be 10 µg/mL Upon testing in the spectroscope the absorbance is was found to be 0.209 and when this solution was placed in a 1.00 cm cuvette and a certain monochromatic radiation of 258 nm radiation was passed through it. Answer the following questions. a. Calculate the specific absorptivity (extinction coefficient), including units, of yeast t-RNA.
b. What will be the absorbance if the solution is diluted to 5 μg/mL?
c. What will be the absorbance if the path length of the original solution is increased to 5.00 cm?

dishwashers don't have rights

explanation:

dishwashers are meant for one thing and one thing only: dishwashing. they belong in the kitchen making sandwiches and cleaning up for the man of their household. if your dishwasher starts acting up just slap it and wait a minute.

a police officer and a ambulance

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.
