cruising far from the sun, we notice that the sun's apparent brightness has dimmed to 10 watts per square meter. we know that the apparent brightness at a distance of 1au is 1000 watts per square meter. how far from the sun are we?

100 watts x 10 apparent brightness = 100 au. Hence we are 100 au far from the sun.Distance is a numerical and sometimes qualitative measure of how far apart an object or point is. In physics and everyday use, the distance may refer to physical length or an estimate based on other criteria. Distance is the overall movement of an object, regardless of direction. The distance can be defined as the distance an object has traveled regardless of its start or end point.Distance is defined as the magnitude or amount of displacement between two positions. Note that the distance between two points is not the same as the distance traveled between the two points. The traveled distance is the sum of the traveled distances between the two positions. Distance traveled is not a vector.Learn more about distance here:-https://brainly.com/question/4931057#SPJ4
