Answer:
is any thing which has mass volume and empty space
Answer: Wavelength associated with the fifth line is 397 nm
Explanation:

= Wavelength of radiation
E= energy
For fifth line in the H atom spectrum in the balmer series will be from n= 2 to n=7.
Using Rydberg's Equation:

Where,
= Wavelength of radiation
= Rydberg's Constant =
= Higher energy level = 7
= Lower energy level = 2 (Balmer series)
Putting the values, in above equation, we get



Thus wavelength λ associated with the fifth line is 397 nm
5.5/-38 / 5.5 = 1/-6.9 x 1.3 = 1.3/-8.98
unit volume/temperature x searching amount
i’d say the temperature would be -8.98 C simply - I don’t know what formula youd use for this
1L=1000 mL,L GOES BOTTOM AND mL GOES TOP,ANSWER SHOULD BE 42700.
