PLEASE HELP An electron moves from n=2 to n=3. Use the Balmer series to find the following; i)wavelength for n=2 ii)Energy for n=2 iii) Wavelength for n=3 iv) Energy for n=3 v) Energy absorbed when moving from n=2 to n=3. (h=6.63*10^-34Js; c=3*10^8m/s) (Hint: ∆E=Ef - Ei where f=final and i=initial)

frequency or wavelenth of em radiation in a vacuum

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

i think the answer is a and b

i wish you luck

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
