Answer: Electron e3 must emit a photon of light in order to drop down from the n=5 to the n=4 energy level.
Explanation:
When an electron drops from a higher energy level to a lower energy level, it releases energy. This energy is emitted in the form of a photon, which is a particle of light. The wavelength of the photon is determined by the difference in energy between the two energy levels.
In this case, the electron is dropping from the n=5 energy level to the n=4 energy level. The difference in energy between these two levels is 2.18 eV. So, the photon that is emitted will have a wavelength of 121.6 nanometers.
The emission of a photon by an electron is a quantum mechanical process. This means that it cannot be predicted exactly when the electron will emit the photon. However, it is possible to calculate the probability of the electron emitting the photon at a given time.
The probability of the electron emitting the photon is greatest when the electron is in the n=5 energy level. As the electron falls to the n=4 energy level, the probability of emitting the photon decreases.
The emission of a photon by an electron can be used to study the structure of atoms and molecules. It can also be used to generate light of a specific wavelength, which is useful in a variety of applications, such as lasers and spectroscopy.

Answer:
The negative influences that scientific knowledge can have on a society is deforestation, pollution, animal suffering (in animal testing), biological weapons, and genetically altered foods.
Explanation:
C. Acceleration is the distance an object travels within a specific unit of time, whereas speed is a measure of the force necessary to change the acceleration of an object.
D. Speed is the distance an object travels within a specific unit of time, whereas acceleration is a measure of the force necessary to change the speed of an objectWhich of the following best describes the difference between speed and acceleration? A. Acceleration is the distance an object travels within a specific unit of time, whereas speed is the rate at which the acceleration or direction of an object is changing.
B. Speed is the distance an object travels within a specific unit of time, whereas acceleration is the rate at which the speed or direction of an object is changing.
C. Acceleration is the distance an object travels within a specific unit of time, whereas speed is a measure of the force necessary to change the acceleration of an object.
D. Speed is the distance an object travels within a specific unit of time, whereas acceleration is a measure of the force necessary to change the speed of an object.
The option that best describes the difference between speed and acceleration is : ( B ) Speed is the distance an object travels within a specific unit of time, whereas acceleration is the rate at which the speed or direction of an object is changing.
Acceleration is the rate of change of velocity with time while speed is the rate of change distance with time.
Acceleration is a vector quantity because it has magnitude and direction while speed is a scalar quantity.
Hence we conclude that Speed is the distance an object travels within a specific unit of time, whereas acceleration is the rate at which the speed or direction of an object is changing.
