it prevents the current from passing through properly causing a surplus of voltage
The energy required by the excitation of the line is:
ΔE = hν = hc / λ
where:
ΔE = energy difference
h = Planck constant
ν = line frequency
c = speed of light
λ = line wavelength
The energy difference must be supplied by the electron, supposing it transfers all its kinetic energy to excite the line:
Therefore,
And solving for v we get:
Plugging in numbers (after trasforing into the correct SI units of measurement):
=9.4 · 10⁵ m/s
Hence, the electron must have a speed of
9.4 · 10<span>
⁵ m/s in order to excite the <span>492nm</span> line.</span>
Answer:
= 30N - 10N = 20N
Please mark as brainliest!
It is appreciated hope this helps!
Explanation:
I have put what a simple free body force diagram that you would need for this question below!
Just swap out the 5N and 3N with 30N and 10N :)
