Upon being struck by 240-nm photons, a metal ejects electrons with a maximum kinetic energy of 1.45 ev. what is the work function of this metal? (a) 3.73 ev (b) 3.13 ev (c) 4.33 ev (d) 4.92 ev

W = 3.73 eV

Explanation:

Given data:

wavelength of photons 240 nm

kinetic energy 1.45 eV

B y using photoelectric equation

Kinetic Energy  =  Photon Energy - work friction

                              = 5.179 eV

                              = 5.18 eV

    = (5.18 - 1.45) eV

W = 3.73 eV

answer: question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step explanation:

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.
