It has both potential and kinetic energy.
Since the ball is falling through the air its going to keep going faster and faster since gravity is pulling it downward so its not going to stop unless it hits something or someone catches it.
The wavelength of the emitted photon is()= 690nm
<h3>How can we calculate the wavelength of the emitted photon?</h3>
To calculate the wavelength of the photon we are using the formula,
Or,
We are given here,
= The energy difference between the two levels = 1. 8 ev= C.
h= Planck constant = Js.
c= speed of light = m/s.
We have to find the wavelength of the emitted photon = m.
Therefore, we substitute the known parameters in the above equation, we can find that,
Or,
Or, m
Or,=690 nm.
From the above calculation we can conclude that the wavelength of the emitted photon is 690nm.

1. The property of a conductor by virtue of which it posses the flow of electric current through it is called resistance.
2. The resistance of a conductor depends on the cross sectional area of the conductor and it's resistivity.
3.This id due to the fact that the resistance of a wire is inversely proportional to the square of its diameter.
4.Due to at high temperatures , the alloy donot oxidize. Alloy doesn't melt readily and get deformed.
Answer:
v = 0.999981c m/s
Explanation:
Using the time dilation equation
T = stationary time = 100 years
T₀ = 11/12 years = 0.917 years
v = speed of travel in the space = ?
c = speed of light = 3 * 10⁸ m/s
v = 299987395.57 m/s
v = 2.99 * 10⁸ m/s
v = 0.999981c m/s
