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

Finding the volume of regular geometric objects uses standard formulas. The volume of a box equals length times width times height, for example. Not every object, however, fits a formula. Water displacement is best only used for irregular shaped objects.
