EZ as pi Jun 13, 2018 # 3.474 xx 10^6# Explanation: scientific notation has only one digit to the left of the decimal point. 2.345 × 10 3 2.345 × 10 −3 5 Answers. Double those figures to get its diameter: 2,159.2 miles (3,475 km), less than a third the width of Earth. So the distance between the earth and the sun is 150 million kilometers. Earth radius is the distance from the center of Earth to a point on its surface. The orbit changes over the course of the year so the distance from the Moon to Earth roughly ranges from 357,000 km to 407,000 km. In scientific notation, you have to find the number between 1 and 10, then multiply it by #10^x#.So the number between 1 and 10 in … That number is written in scientific notation. The moon's mean radius is 1,079.6 miles (1,737.5 kilometers). Relevance. There is one digit to the left of the decimal point -- 2 -- and it is not 0. Review of the Rules of Exponents. We can express this very wide range of numbers by using "Scientific Notation" or "Powers of Ten Notation". A parsec (pc) is about 30,856,775,814,671,900 meters, or approximately 3.09 × 10¹³ km. Earth radius is the distance from the center of Earth to a point on its surface. For expressing them. To multiply two numbers expressed as powers of ten, you need only multiply the numbers out front and then add the exponents. That number is written in scientific notation. If there are no numbers out front, as in 100 × 100,000, then you just add the exponents (in our notation, 10 2 × 10 5 = 10 7). Instant free online tool for Sun's radius to meter conversion or vice versa. Find the approximate surface area of the moon.Please give your answer in scientific notation … meters. The moon's mean radius is 1,079.6 miles (1,737.5 kilometers). You are probably already familiar with this notation. Optical ground-based telescopes are typically limited to resolving features about 300 km (186 miles) across when Earth and Mars are closest because of Earth’s atmosphere. There are 1,000 meters in a kilometer. In scientific notation, that would be 6.37 x 10^3 km. RoofingPrincess. The mass of the Moon is 73,000,000,000,000,000,000,000 kg What is this written in Scientific notation (Standard form)? In general, a number written in scientific notation will be multiplied by 10 raised to an "exponent." A nanometer is 0.000000001 meter. Algebra -> Customizable Word Problem Solvers -> Numbers-> SOLUTION: The radius of the moon is approximately 1.773 x 10^3 km. Its value ranges from 6,378 km (3,963 mi) at the equator to 6,357 km (3,950 mi) at a pole. Then all the other significant digits are written to the right of the decimal point. So 6,370,000 m would equal 6370 km. Answer Save. Scientific notation is not only compact and convenient, it also simplifies arithmetic. Double those figures to get its diameter: 2,159.2 miles (3,475 km), less than a third the width of Earth. In scientific notation the Sun's mass becomes: M Sun = 1.989 x 10 33 gm. In general, a number written in scientific notation will be multiplied by 10 raised to an … The radius of a hydrogen atom is 0.00000000012 meters. Basis of expression for length, size, distance in physical sciences is the meter. Consequently,scientists use a "shorthand" way (scientific or exponential notation) to write very large or very small numbers. N × 10n meters, where N = __and n =__ . What is distance to Sun in meters? However, Earth is not quite a sphere. Mean values at opposition from Earth Distance from Earth (equator, km) 378,000 Apparent diameter (seconds of arc) 1896 Apparent visual magnitude -12.74 * These represent mean apogee and perigee for the lunar orbit. In Physics, as in all of Science, we encounter numbers that are incredibly small and others that are incredibly large. Illustration of idea: . 2.345. Meter stick. Work with numbers using scientific notation. Also, explore tools to convert Sun's radius or meter to other length units or learn more about length conversions. Lv 7. radius (r) = 1.773x10^3 km MOON is in shape of sphere surface area of moon (sphere) = 4*pi*r^2 = = = = Result: 39.4394x10^6 km ^2 A nominal Earth radius is sometimes used as a unit of measurement in astronomy and geophysics, denoted in astronomy by the symbol R ⊕. Scientific Notation. One parsec represents the distance from the Sun to an astronomical object, such as a planet, a star, a moon, or an … The Sun's radius to meter [m] conversion table and conversion steps are also listed. The distance between Earth and its moon is 384000000 meters. Best Answer: A. 826 3 The width of a DNA molecule is about 2.5 nanometers. Radius, diameter and circumference The radius of Earth at the equator is 3,963 miles (6,378 kilometers), according to NASA's Goddard Space Flight Center . A nominal Earth radius is sometimes … 9 years ago. Work with numbers using scientific notation.
