The ratio of the maximum photoelectron kinetic energy to the work function will be 3:1.
<h3 /><h3>What is the photoelectric effect?</h3>When a medium receives electromagnetic radiation, electrostatically charged particles are emitted from or inside it.
The emission of ions from a steel plate when light falls on it is a common definition of the effect. The substance could be a solid, liquid, or gas; and the released particles could be protons or electrons.
A particular metal emits photoelectrons when exposed to light with energy three times its work function:
The ratio of the maximum photoelectron kinetic energy to the work function will be;
Hence, the ratio of the maximum photoelectron kinetic energy to the work function will be 3:1.

Answer:
The change in temperature is
Explanation:
From the question we are told that
The temperature coefficient is
The resistance of the filament is mathematically represented as
Where is the initial resistance
Making the change in temperature the subject of the formula
Now from ohm law
This implies that current varies inversely with current so
Substituting this we have
From the question we are told that
Substituting this we have
=>
