Answer:
a
b
Explanation:
From the question we are told that
The diameter is 
Generally the radius electron orbit is mathematically represented as
=> 
This radius can also be represented mathematically as
Here n is the quantum number and 
is the Bohr radius with a value
So
=>
Generally the angular momentum of the electron is mathematically represented as
Here h is the Planck constant and the value is 
m is the mass of the electron with values 
So
Answer:
electrical conductivity in liquid solutions depends on the availability of free ions.
Answer:
Explanation:
The vertical component of velocity remains same as the free fall. The vertical motion of the projectile is same as the free fall motion.
D. Redefine the machine’s system boundaries.
The Law of Conservation of Energy states that energy can't be created not destroyed. Energy, however, can be changed from one form to another. The law applies to isolated systems only. By redefining and expanding the system (including all factors affecting it) , the machine's ability to do work should improve.
Medium.
Medium is matter, and electromagnetic waves do not need matter to travel. Just like the sun, its plasma light travels across space to reach us.
