It has been calculated that the observed colored lines in a hydrogen line spectrum correspond to the relaxation of the electron from higher energy level down to the second energy level. Based on this information and how the wavelengths are ranked by energy, match each spectrum line wavelength to its corresponding transition.

step-by-step explanation:

whole numbers, zero or greater

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.
