I have a note here that might help you solve the problem on your own:
According to the law of conservation of energy
The energy of the photon is used in overcoming the workfunction of the metal, and the excess energy goes as the kinetic energy of the electron.
<span>Photon Energy = Work function of Cs + KE of electron
</span>
I hope my guide has come to your help. God bless and have a nice day ahead!
The lead ball will float with about 17% of its volume above the surface of the mercury.
We know that density is defined as mass per unit volume of a substance. The density of a substance is an intrinsic property which can be used to identify a substance.
Given that Lead is less dense that mercury, we know that lead will float on mercury. Since the density of mercury is 13.6 g/cm3 and that of lead is 11.3 g/cm3, lead ball will float with about 17% of its volume above the surface of the mercury.

A hydroelectric dam or a hydro-power plant.<span />
THe best answer would be observation because you can see that all 3 are made up of water which you don't need to infer because you have the proof when you look at all 3 different types of precipitation.
I hope this helps you out.
