tankabanditka [31]

Answer:

454

Step-by-step explanation:

The formula for this arithmetic sequence is: 9n+4

1st term: 9(1)+4 = 13

2nd term: 9(2)+4 = 22

3rd term: 9(3)+4 = 31

4th term: 9(4)+4 = 40

A local am radio station broadcasts at a frequency of 764 khz. calculate the energy of the frequency at which it is broadcasting
pentagon [3]
The frequency of the emitted radio waves is:
f=764 kHz = 7.64 \cdot 10^5 Hz

The energy of a photon is given by:
E=hf
where h is the Planck constant and f is the photon frequency. Using the frequency given by the problem, we can find the energy of each photon of this radiation:
E=hf=(6.6 \cdot 10^{-34} Js)(7.64 \cdot 10^5 Hz)=5.04 \cdot 10^{-28} J=5.04 \cdot 10^{-31} kJ
