Explanation:
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).
Answer:
The maximum kinetic energy of the electrons emitted from the surface will be greater.
Option 3 is correct.
Explanation:
Given that,
Wavelength 
Wavelength 
We need to calculate the energy for first wavelength
Using formula of energy
Put the value into the formula
We need to calculate the energy for second wavelength
Put the value into the formula
So, E₂>E₁
Hence, The maximum kinetic energy of the electrons emitted from the surface will be greater.
Let's give it a whirl .....
When the entire group of forces acting on an object is balanced,
the individual forces all add up to zero, and the effect on the object
is the same as it would be if there were no force at all acting on it.
No force on it means no acceleration ... no change in speed or
direction of motion.
No change in speed or direction of motion means constant velocity.
