A conceptual model is based off of
Klio2033 [76]
<h2>Answer</h2>

Tha conceptual model depends upon the process flow.

<h2>Explanation</h2>

The conceptual model is actually used in the system to stimulate, understand or explore the subject for the better understanding of people. As it consists of different constituents as validation, implementation, accreditation etc. can be affected by the process flow. The process flow has actually consisted of the management, monitoring of objects for specific subject and scales under these monitoring or management are proceedings. As these scales of process flow effects, the objectives of the task impacts.

Lerok [7]

Answer:

E = 1.24MeV

Explanation:

The photon travels at the speed of light, 3.0 × 10^{8} m/s, and given that its frequency = 1 picometer = 1.0 × 10^{-12} m.

Its energy can be determined by;

E = hf

  = (hc) ÷ λ

where E is the energy, h is the Planck's constant, 6.626 × 10^{-34} Js, c is the speed of the light and f is its frequency.

Therefore,

E = (6.626 × 10^{-34}× 3.0 × 10^{8}) ÷ 1.0 × 10^{-12}

  = 1.9878 × 10^{-25} ÷ 1.0 × 10^{-12}

E = 1.9878 × 10^{-13} J

But, 1 eV = 1.6 × 10^{-19} J. So that;

E = \frac{1.9878*10^{-13} }{1.6*10^{-19} }

  = 1242375 eV

∴ E = 1.24MeV

The energy of the photon is 1.24MeV.
