The Earth's surface area is 5.10 times 10^8 Km^2 : It's crust has an average thickness of 35 Km. What is the volume of the earth's crust? If the average density of the crust in 2.8 g / cm^3, what is the mass of the crust in Kg? I...
The circumference of the Earth is approximately 40,000 kilometers.(地球的周长约为40,000公里。) The circumference of this tire is perfect for my bike.(这个轮胎的周长非常适合我的自行车。) To find the circumference of a circle, you need to know its radius.(要知道一个圆的周长,你需要知道它的...
What is the radius of the Earth, in kilometers and in miles? At ground level g is 9.8 m / s 2 suppose the earth starts to increase its angular velocity. How long would a day be when people on the equator were just thrown off. ...
Attempts have been made to measure the circumference of the earth since the time of Aristotle. The calculation that Columbus was relying on led him to think he could reach China by sailing west more quickly than by sailing east. But that measurement had calculated the earth's circumference as...
Circumference of a Circle: DefinitionThe circumference is the length of the boundary of a circle. It is also known as the “perimeter” of a circle. Since it represents length, it is measured in units of lengths such as feet, inches, centimeters, meters, miles, or kilometers.If...
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 ...
Highest point: 452 meters above sea level. 10.4 kilometers in circumference. Point le plus élevé : 452 mètres au-dessus du niveau de la mer. Literature “There was a rock, not small in circumference, and very high. “Elle était bâtie sur un grand rocher dont le sommet qui ...
By measuring the shadow angle at the top of the Obelisk at noon on the same day in Alexandria and taking into account the distance between the two cities using a simple mathematical formula, Eratosthenes calculated the Earth's circumference at about 40,000 kilometers. The calculation was proved...
Chapter 31. The Possibility of a “Finite” and Yet “Unbounded” Universe1920 This means thecircumferenceis about 1000 meters, so v is 1000 meters per minute, which yields a simulated gravity about 1/6 of Earth's -- the same as the moon (though the people inside move as though the gr...
The circumference of the earth is 25,000 mi at the equator. What is the circumference in kilometers? in meter? The circumference of the earth at the equator is 40,000 km. This value is precise to two significant figures. Write this in scientific notation to express correc...
