Answer:
λ = 3.1824 10-25 m
Explanation:
To release the electron from the power well the absorbed photon electro must be greater than or equal to the energy of the electron in the power well
The photon energy is E_photon = 0.625 J
The speed of light is
c = λ f
Let's use Planck's equation
E = h f
We substitute
E = h c / λ
λ = h c / E
λ = 6.63 10-34 3 108 / 0.625
λ = 3.1824 10-25 m
Answer:
The deviation in path is 
Explanation:
Given:
Velocity

Electric field

Distance
m
Mass of electron
kg
Charge of electron
C
Time taken to travel distance,


sec
Acceleration is given by,





For finding the distance, we use kinematics equations.

Where
because here initial velocity zero


m
Therefore, the deviation in path is 
The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation and the centrifugal force. In SI units this acceleration is measured in metres per second squared or equivalently in newtons per kilogram.
Answer:
A: Ions are attracted to each other → Electrons are transferred → An ionic compound forms. B: An ionic compound forms → Ions are attracted to each other → Electrons are transferred. C: Electrons are transferred → Ions form → Ions are attracted to each other.
