Introduction A wind instrument is an instrument that produces sound by manipulating air through varying the wind pressure passing through the air outputs of the device (Berg and Stock, 27). These devices are heavily dependent on pressure as well as the size and shape of the instrument (pg. 28). A good example of a wind instrument is the organ pipe. It is a tool that produces a specific pitch when pressurized air is driven through it. Organ pipes usually exist in sets, where each is confined to produce a specific tune. Normally, it is a keyboard device that is ...

Aims

Studying the vibrational modes of organ pipes Introduction Sound is a vibration that arises from a mechanical wave of pressure and displacement, through a medium like air or water (Berg and Stock, 23). The reception and perception of these waves by the brain is referred to as sound. On the other hand, acoustics deals with the study of these mechanical waves in matter (pg. 40). In this experiment, the organ pipe is the main target of discussion. This is a sound producing wind instrument that resonates at a specific pitch when pressurized air is driven through it. A complete ...

Not all studies are created equal, and when it comes to research, the two prominent research methodologies employed are those of qualitative research, and quantitative research methodology. While both these methodologies have their unique characteristics in the way they are used to arrive at a possible result, quantitative research emphasizes on the number of volumes of study to arrive at a particular answer to a research. Journals, websites, guides, reports, and publications are all part of the quantitative research paradigm. Aliaga and Gunderson (2000) describe quantitative research method as “understanding a phenomenon by collecting existing numerical data that are analyzed using mathematically-based methods” ( ...

What are the effects of the internet and social networks on Cyber bullying and to what extent has Cyber bullying been experienced among the youths?

Thesis Statement

Bullying is not a new terminology, and especially among the youths. It is a vice that has been in existence for long but one that is manifesting itself on new platforms with the advancement in technology.
