The hi line of the balmer series is emitted in the transition from n = 3 to n = 2. compute the wavelength of this line for l h and 21. note: these are the electronic hydrogen and deuterium atoms, not the muonic forms.]

Explanation:

The Hi line of the Balmer series is emitted in the transition from n = 3 to n = 2 i.e. and

The wavelength of Hi line of the Balmer series is given by :

So, the wavelength for this line is 550 nm. Hence, this is the required solution.

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts
