The circumference of the earth is 25,000 mi at the equator. What is the circumference in kilometers? in meter? Equator: The equator is one of the regions on our planet Earth. If we model the Earth as having the north pole at the top and the s...
29.C,细节理解题,根据第二段"He calculated that the circumference(圆周) of the Earth was 28,600 miles(46,000 kilometers). "他计算出的地球的圆周周长是28600英里(46000公里),可知,他确信地球是圆的,故sphere是一个球体,故选C.30.B,词义猜测题,根据第二段大意可知,Eratosthenes 测算出地球的周长,可知...
He used the sun and geometry (几何学) to figure out the size of the Earth. He calculated that the circumference (圆周) of the Earth was 28,600 miles ( 46,000 kilometers). Actually, The true size of the Earth is 25,000miles (40,000 kilometers ).Eratosthenes's measurement was wrong,...
The circumference of the earth is 25,000 mi at the equator. What is the circumference in kilometers? in meter? a) What is the circumference of Earth at its equator? b) What is 1.00 ppm of this length? The average distance from the Earth to the Sun is 150 megameters. What is this...
At the same time, the European Organization for Nuclear Research (CERN) is conducting a feasibility study on the Future Circular Collider (FCC). The FCC, with a circumference of 91 kilometers, is planned to replace the existing 27 - kilometer - long Large Hadron Collider (LHC) at a cost ...
At the equator, the Earth’s surface moves 40,000 kilometers in 24 hours. That is a speed of about 1040 miles/hr (1670 km/hr). This is calculated by dividing the circumference of the Earth at the equator (about 24,900 miles or 40,070 km) by the number of hours in a day (24)...
He found out that the circumference (圆周) of the Earth was 28.600 miles(46.000 kilometers). The true size of the Earth is 25.000 miles (40,000 kilometers).Eratosthenes' 26 was wrong, but it was very close to the truth.Many centuries ago, people made 27 of the Earth. However, they ...
The moon is its satellite.The radius (半径) of the earth's equator is6,378.137 km, the polar (极) radius is 6,356.752 km,and the circumference (周长) of the equator is about40,076 km. The surface (表面) area of the earth is 510million square kilometers(平方米),of which 71% is ...
687 miles. Archimedes was the closest to guessing the accurate circumference of the Earth, which is 40,075 kilometers. Erastosthenes, a Greek scholar living in Egypt, observed the position of the sun during the summer solstice and calculated the approximate circumference of the Earth using the ...
The circumference of the earth is 25,000 mi at the equator. What is the circumference in kilometers? in meter? The density of air under ordinary conditions at 25 degrees Celsius is 1.19 g/mL. How many kilograms of air are ...
