Answer:
1. 389.2 times farther
2. Scientific Notation
Step-by-step explanation:
Given that
Distance from moon to earth = 384,400 km
Distance from sun to earth = 149,600,000 km
Therefore, distance from sun to moon
= Distance from sun to earth less distance from moon to earth
So,
Distance from sun to moon = 149,600,000 km - 384,400 km
= 149,215,600 km
Number of times the earth is farther from the sun = 149, 600, 000 ÷ 384, 400
= 389.1779
= 389.2 times farther
Again, from the data, the diameter of the sun can be estimated by
= 3476 × 389.2
= 1.35 million km
NOTE: All these are estimated answers from the data provided in the question.
Scientific Notation is a way used in expressing numbers that are too big or too small to be conveniently written in decimal forms. It's also called Standard form in some areas of the word.
