Explanation:
Given data
For Part (a)
Starting with the -ve acceleration of the body (opposite to the gravitational force)
Using equation of motion
For Part (b)
Using the result in Part (a) we can substitute in other equation of motion to get time t:
For Part (c)
At state 2 where vo=0m/s and the acceleration is positive (same direction as the gravitational force)
Answer:
Explanation:
The energy of the emitted photon is inversely proportional to its wavelength, according to the equation:
where
is the Planck's constant
is the speed of light
is the wavelength
This means that the biggest energy is released when the wavelength is the shortest. For a photon of visible light, the shortest wavelength is
So, substituting into the equation, we find the corresponding energy:
