What are the 3 components of acoustics?
What are the 3 components of acoustics? The entire spectrum can be divided into three sections: audio, ultrasonic, and infrasonic. The audio range falls between 20 Hz and 20,000 Hz. This range is important because its frequencies can be detected by the human ear. This range has a number of applications, including speech communication and […]

What are the characteristics of an activated complex?
What are the characteristics of an activated complex? In a reaction with an activated complex, A and B form the complex A-B. The complex only forms if sufficient energy (the activation energy) is present. The energy of the activated complex is higher than that of either the reactants or products, which makes the activated complex […]
