The Earth's inner core is the Earth's innermost part. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 70% of the Moon's radius.[1][2] It is composed of an iron–nickel alloy and some light elements. The temperature at the inner core's surface is approximately 5,700 K (5,430 °C), which is about the temperature at the surface of the Sun. (i found this i hope it helps)

A capacity of wind farm is 3 gigawatts (GW). Assuming that the power plant can operate at full capacity for 5,000 hrs/yr, how ma
den301095 [7]

Answer:

1.5x10^10 KWh

Explanation:

Data obtained from the question include:

Power (P) = 3GW

We need to convert 3 gigawatts (GW) to Kilowatts (KW) in order to obtain the desired result. This is illustrated below:

1 GW = 1x10^6 KW

Therefore, 3 GW = 3x10^6 KW

Time (t) = 5000 hrs/yr

Energy (E) =?

Power is simply the amount of energy transferred per unit time. It can be expressed mathematically as:

Power (P) = Energy (E) / Time (t)

P = E/t

Applying the above formula, we can calculate the energy in kWh of electricity that can be produced by the plant in one year. This is illustrated below:

P = E/t

3x10^6 KW = E / 5000 hrs/yr

Cross multiply to express in linear form as shown below:

E = 3x10^6 KW x 5000 hrs/yr

E = 1.5x10^10 KWh

Therefore, 1.5x10^10 KWh of electricity can be produced by the plant in one year.

Why did the U.S. dollar become a substitute for gold in international markets during the 20th century?
Leviafan [203]

Answer:

The correct answer is C. The United States declared that the U.S. dollar was fiat currency .

Explanation:

Fiat money is money that has no inherent value. The value of fiat money is based on the institution that issues this money saying that it is worth something. In practice, the department is always a state. Fiat money has no coin base or is said to have a paper coin base and has only limited coverage of, for example, a gold reserve. Most currencies in the world today are fiat money, such as US dollars.

When in 1971, during the Nixon government, America abandoned the dollar's parity with the gold standard, the dollar became a fiat currency, and with the passage of time, the main international reserve currency.
