The electron in a ground-state H atom absorbs a photon of wavelength 97. 25 nm. Energy level till where the electron move is 4
Rydberg's equation is formula which signifies relation of wavelength of incident photon and the energy level.
Rydberg's equation is used to find out the relation between the wavelength and the Energy Levels:
1/λ = RZ² (1/n₁² - 1/n₂²)
where, λ is wavelength = 97.25 nm
R is the Rydberg constant = 1.0967 × 10⁷ m
n₁ is the initial energy level i.e. the Ground state, n₁ = 1
n₂ is the higher energy level
On substitution of the above value:
1/97.25 × 10⁻⁹ = 1.0967 × 10⁷ ( 1 - 1/n₂²)
On solving,
⇒ n₂ = 4
Hence, the higher energy level is 4

The frequency of a wave is equal to the reciprocal of its period:
where f is the frequency and T the period.
The violin string of our problem emits a note with frequency f=440 Hz, so if we re-arrange the previous equation, we can find the period of the string's oscillation:
Answer:
<h2>12,960 m</h2>
Explanation:
The distance covered by an object given it's velocity and time taken can be found by using the formula
distance = velocity × time
From the question
2 hours = 7200 s
We have
distance = 1.8 × 7200
We have the final answer as
<h3>12,960 m</h3>

Answer:
0N
Explanation:
The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.
