Answer:
5,865,696,000,000
Explanation:
31,536,000 seconds in a year. 31,536,000×186,000=5,865,696,000,000
Answer:
0.7515875 eV
Explanation:
f = Maximum frequency =
h = Planck's constant =
W = Work function = 2.52 eV
Converting to Joules
Maximum photon energy is given by
Maximum Kinetic energy is given by
Converting to eV
The maximum kinetic energy of electrons ejected from this surface is 0.7515875 eV
The range of frequencies for which no electrons are ejected is
To find the x component use the following formula, where Ф = theta = the angle 'a' makes with the x axis.
