4. Snow removal, as its snows a lot in Pennsylvania.
5. For number 5 please tell me which services the company offers & keep in mind the weather patterns are pretty hot & sunny in Florida, especially during the summers. If the company provides services (such as snow removal) Florida would hardly need any, causing the company to make less profit.
Good luck & please be sure to try your best. You got this!

If titanium is irradiated with light of 233 nm, what is the maximum possible kinetic energy of the emitted electrons?
Vsevolod [243]

Answer:

K=1.61×10−19 J

Explanation:

In the question data given is as follows:

   Wavelength of the is given as light (λ)=233 nm

  while the worrk-function of the titanium given as (ϕ)=6.93×10−19 J

but for the energy imparted due to the light will now be

E=hcλE, then

E=hcλE=(6.63×10−34)(3×108) / 233×10−9

E=8.536×10−19 J

Now, the energy imparted is given by

E= ϕ + K

8.536×10−19= (6.93×10−19) + K

K=1.61×10−19 J

Then,

K is the kinetic energy of the electrons
