Particles vibrate when frozen when it boils it moves like you had 4 monsters in the morning
Answer:
Kinetic energy:
Velocity:
Explanation:
From the equations of the photo-electric effect,
We know:
Where,
1. is the Planck's constant which is
2. are the frequency of light emitted and threshold frequencies respectively.
3. is the kinetic energy of the electrons emitted.
By fact, we come to know that the threshold frequency of Zn is 300nm
And also
Where ,
1. is the speed of light
2. is the wavelength.
Thus,
Now to find velocity:
