<span>Both radar and sonar locate objects from the echo of a signal that is bounced off the object. Radar uses radio waves, which are a type of electromagnetic energy. Sonar uses the echo principle by sending out sound waves underwater or through the human body to locate objects. Sound waves are a type of acoustic energy. Because of the different type of energy used in radar and sonar, each has its own applications.</span>

A country whose economy can be described as "developing" is most likely to engage in which kind of economic activity.
Leya [2.2K]

The correct answer is - industry.

The developing countries are most often occupied with making the economies heavily focused on the industry, so the countries engage into a big industrialization process.

The industries are usually based around manufacturing of the natural resources that the country has, and most often those are the metal ores, the agricultural products, creating materials...

The developing countries usually have a relatively big economic growth, and that is due to the bad economic basis that they had as a starting point.

what is the definition of economic growth? an increase in the amount of money remitted by foreign workers to their native countr
schepotkina [342]

The correct answer is - a rise in the total amount of goods and services produced within the borders of a nation.

The economic growth is is defined by the economic activity of the nation, how much is it producing, as well as the quality of the production, of both goods and services within its borders.

If a nation starts to produce more goods, and has where to sell those goods, that automatically, the nation is making bigger profit by having and influx of money in its economy. The same goes for the services, if they are increasing and their quality is becoming better (which is a huge factor for the increase), more and more money will flow into this sector, thus giving it a big economic injection for the nation.
