IM PRETTY SURE IT IS D !! IF ITS WRONG IM SORRY THAT WHAT
I GOT
No, its not possible. Let's go back to 4th grades' basic science.
"Energy can not be created or destroyed."
This applies to everything, even atoms!
Have a great day! ❤
Protons always has a positive charge
Answer:
The equation for the Kinetic Energy,
, of the photo-emitted electrons is given as follows;

Please find attached the required plot of the kinetic energy versus the frequency
Explanation:
The equation for the Kinetic Energy,
, of the photo-emitted electrons is given as follows;

Where:
h = Planck's constant = 6.63×10⁻³⁴ J·s
f = Frequency
BE = Binding Energy = 2.71 eV for Calcium metal
f₀ = Threshold frequency for the material
The ionization energy is the energy required to free an electron from an isolated atom
