{\qquad\qquad\huge\underline{{\sf Answer}}}

Here we go ~

Energy difference btween the two electronic states can be expressed as :

{ \qquad \sf  \dashrightarrow \: \Delta E = h\nu}

[ h = planks constant,{\: \nu }= frequency ]

\qquad \sf  \dashrightarrow \:214.68 = 39.79 \times 10 {}^{ - 14}  \times  \nu

\qquad \sf  \dashrightarrow \: \nu =  \cfrac{214.68}{39.79 \times 10 {}^{ - 4} }

\qquad \sf  \dashrightarrow \: \nu =  \cfrac{214.68}{39.79 }  \times 10 {}^{14}

\qquad \sf  \dashrightarrow \: \nu  \approx  5.395 \times10 {}^{14}  \:\:hertz

The unit conversion between rankine and kelvin is (linear, exponential, quadratic, none of the above)?
diamong [38]

Answer:

Unit conversion between Rankine and Kelvin is linear.

Unit conversion between degree Celsius and degree Fahrenheit is linear.

Explanation:

Relation between rankine and Kelvin is

R\ =\ \dfrac{9}{5}\ K

So, the plot between Rankine and Kelvin is a straight line with zero intercept and has a slope having value \dfrac{9}{5}.

Relation between degrees Celsius and degrees Fahrenheit is given by

^{\circ}C\ =\ \dfrac{5}{9}\ (^{\circ}F\ -\ 32)

So, the plot between degrees Celsius and degrees Fahrenheit is a straight line with slope \dfrac{5}{9} and negative intercept of \dfrac{160}{9}.

What law is known as the law of action-<br> reaction?
Molodets [167]

Law of Action and Reaction mean "To every action there is equal and opposite reaction.

Explanation:

It is Newtons third law which explained few  things such as :-

1. The nature of the forces between the two interacting objects.

2. According to this law , the force that is exerted from Object-1 to Object-2 is said to be equal in magnitude and opposite to the direction to the force exerted to object 2 upon object 1.

3. Eaxmple - As we push against the wall - Action , the wall in return opposes equal force to resist the pressure of the hand - Reaction.
