The Sun is a main - sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen each second.
Answer:
Option(2) is the correct answer to the given question.
Explanation:
The barometers are used to determine the air pressure at the present location. If the barometers shows high pressure this simply means that weather is clear also the barometers showing the low pressure that directly proportional to the weather is bad.
- In the bad whether there are lots of the chances of raining.
- All the other options are not correct for the bad weather that's why these are incorrect option .
Answer:
C. Low-frequency seismic waves cause more ground acceleration than do high-frequency waves.
Explanation:
Low-frequency seismic waves covers more distance as compared to high-frequency waves because high frequency wave provide more energy to the medium while low frequency waves supply less energy to the medium so which makes the wave to go further. Lower frequency waves "penetrate" into a materials better, because energy particles having lower frequencies having less energy and they pass through the medium without interacting with the matter.
The correct answer is - secondary economic activity.
The developing countries are trying to boost and develop their economies by developing the industry. They build lots of industrial facilities, factories, and instead of selling the raw materials to the more developed countries, they start to use the raw materials for their own purpose and manufacture them into products ready for the market. This production can include anything from creating steel from the iron ore, make juices from the fruits and vegetables, use the cotton for making clothes etc., so all in all making final products that directly end up on the market, thus making a bigger profit.
Answer:
Population density.
Explanation:
Population density is a statistical data that allows graphing the number of people living in a given territory, dividing the number of inhabitants of that territory by its size, usually in square kilometers or square miles.
Thus, the more the population increases in a territory, the more its population density will increase. An example of territories with a high population density is Hong Kong, with about 7,000 inhabitants per square kilometer, while an example of a nation with a low population density is Canada, with 4 inhabitants per square kilometer.
