Answer:
pretty sure it's true....
Answer:
3.5434 eV
Explanation:
For a particle with kinetic energy E and mass m , the wavelength associated is given by the following relation,

E = 
Putting the values we get
E = 
=1.063 x 10⁻²¹ J
= .0066 eV.
Energy of¹light in terms of eV
= 1244 / 350 = 3.55 eV.
Work function = 3.55 - 0.0066 = 3.5434 eV.
Answer:
Workdone = 1250Nm
Explanation:
<u>Given the following data;</u>
Force, F = 500N
Distance, d = 2.5m
Workdone is given by the formula;
Substituting into the equation, we have
Workdone = 1250Nm
Therefore, the actual work done by the worker is 1250 Newton-meter.
