The work function has the formula
E = h v
where
E is the energy
h is the constant
v is the frequency
Since the given is wavelength, we use the relationship between frequency and wavelength
v = c / λ
where
c is the speed of light
<span>λ is the wavelength
</span>
So.
E = h c / <span>λ
h = E</span><span>λ / c = 1.25 eV (475x10-9m) / (3x10^8 m/s)
h = 1.9792 x 10^-15
The work function is:
E = 1.9792 x 10-15 v

Answer:
a i belive
Explanation:
the univerce is VERY large so a, if im wrong i apologise :(
Answer:
2.2 m/s^2
Explanation:
Acceleration = Force / Mass
= 7.92 / 3.6 = 2.2m/s^2
Hope this help you :3
