Options:
A) how fast the wave is traveling
B) the frequency of the sound wave
<u>C) the power of the sound wave per unit area </u>
D) the mass of the wave divided by its volume
Sound intensity refers to the amount of energy and power that is carried by a sound wave in a specific position or area in which it travels. In other words, it is the power and strength of a sound wave per unit area. It could be measured in decibels (dB) or, in other cases and less commonly, in watts per meter squared.

Westward expansion profoundly changed American society. As the nation grew, more people looked west in order to obtain cheaper land. Once there, they developed communities with stores and professional positions, such as blacksmiths and lawyers, many of these Western towns were some of the fastest growing places in the United States. These people in the West also aspired to own manufactured goods, and the United States was beginning to get into the Industrial Revolution after the Revolutionary War.
Before the war and immediately thereafter, American manufacturing was considered secondary to British work. After the war, Americans looked to develop their own manufacturing as a way to grow industries at home and also as a source of national pride. More people would work in American factories in the period leading up to the Civil War and after the war this number would increase significantly with more European immigration.
Most of the factory jobs were in the North, but in order to facilitate transportation of raw materials and finished products, the US government undertook a program of internal improvements called the American System which improved railroads and canals in most of the United States. This benefited the West as it made transportation of goods and people easier; it also benefited Americans as a whole, as American manufacturing increased and new jobs were being created.
Answer:
Over the past 30 years, an increase in the price and production of cocoa, gold, and oil helped transform Ghana: real GDP growth quadrupled, extreme poverty dropped by half, and in 2011, Ghana moved to a Lower Middle-Income Country status. The fundamental question is: How can this impressive development, anchored firmly on natural capital, continue to deliver gains in macroeconomic growth and poverty reduction?
The recent World Bank Ghana Country Environmental Analysis (CEA) responds by providing the scale, scope, and economic effects of environmental degradation on society. Air, plastics, and water pollution affect health and hygiene; gold mines, unmanaged solid waste, and contaminated sites release hazardous chemicals; land degradation, deforestation, and overfishing heavily impact livelihoods and limit drivers of growth.
According to the CEA, environmental degradation costs $6.3 billion annually or nearly 11% of Ghana’s 2017 GDP . Non-renewable resources such as gold and oil cannot sustain growth as resources deplete while renewable resources like cocoa, timber, and other tree and food crops, depend on good environmental stewardship. There are clear signs and scientific evidence that the erosion of the natural capital may put at risk growth, livelihoods, and human health.
