Answer with Explanation:
We are given that
Threshold wavelength,
a.Work function,
Where
Using the formula
b.Wavelength,
Hence, the maximum kinetic energy of an electron emitted=
Polarization of light is achieved by passing the light through a polarizer which causes the light to vibrate in only one direction.
<h3>What is polarization of light?</h3>
The question is unclear but I will try to explain what is meant by polarization of light. We know that light is an electromagetic wave and vibrates in all directions.
The polarization of light enables light to vibrate in a specified direction. This is achieved by passing the light through a polarizer which causes the light to vibrate in only one direction.

Answer:
C. In the direction that energy flows though the food chain
Explanation:
Strawberry > Cricket > Mouse > Owl. Energy is going this way
Stress = force / area
= 4.8 x 10³ / 1.2 x 10^-4
= 4 x 10⁷ N /m²
YOUNGS MODULAS = stress / strain
= 4 x 10⁷ / 1.2 x 10^11
= 3.3 x 10^-4
INCREMENT OF LENGTH = longitudinal length x intitial length
= ( 3.3 x 10^-4 ) x 4
= 13.2 x 10^-4 m
= 13.2 mm
