Answer:
Energy is 10,000 Joules.
Explanation:
It is given that, a 10,000 watt radio station transmits at 535 kHz. We have to write the number of joules transmitted per second.
We know that number of joules transmitted per second is called the power. Its SI unit is watts. Mathematically, the power of radio station is given by :
Where
W is the work done by radio station
t is the time taken.
According to relation :
So,
Hence, energy per second is 10,000 Joules.

169/4 ft/min.
Explanation:
See the attached picture.
Explanation :
When an electron jumps from one energy level to another, the energy of atom gets changed.
If a photon gets absorbed, the electron will move to higher energy levels and then fall back to the lower energy levels. Then each time a photon will be absorbed whose energy is given by difference between the initial and final energy levels i.e
In Balmer series, the transition is from higher energy levels to n = 2.
So, the necessary condition for Balmer series is that the electron should be at first excited state or n = 2 level as shown in figure.
