Answer:
The time taken is
Explanation:
From the question we are told that
The length of the speed ramp is
The speed of the speed ramp is
The time taken to cover the distance is
The walking speed( when not on the speed ramp) required to cover the 104m is mathematically represented as
Substituting values
The speed required to cover the 104m distance when on a speed speed ramp is mathematically represented as
substituting values
Now the time taken to travel the 104m distance when walking on the speed ramp is mathematically evaluated as
Answer:
Explanation:
In this problem we can use Bohr's atomic model, to deal with the electronic transition, so we can have transitions between two given states.
ΔE = -E₀
Lower state final state energy
Fundamental first excited state ΔE₁ = -2.4 - (-4.7) = 2.3 eV
Fundamental second excited state ΔE₂ = -1.0 - (-4.7) = 3.7 eV
Fundamental third excited state ΔE₃ = -0.3 - (-4.7) = 4.4 eV
As they indicate that there are no electrons in the excited states these are the only possible transitions.
When a wide range of light strikes, the frequencies of these energies are absorbed and observed as black bands (absence of radiation) in the spectrum.
