The nearest star to our solar system, is 4.3 light-years away Express this distance in miles in scientific notation
well one light-year is 5.879 * 10^12 miles, so ...
4,200,000
To express the distance of 4.3 light-years in miles using scientific notation, we need to know the conversion factor between light-years and miles.
The speed of light is approximately 186,282 miles per second. In one year, there are approximately 31,536,000 seconds. Therefore, we can calculate the number of miles in one light-year as follows:
186,282 miles/second x 31,536,000 seconds/year = 5,878,625,152,000 miles/year.
Now, we can convert the distance of 4.3 light-years into miles:
4.3 light-years x 5,878,625,152,000 miles/year = 25,265,736,332,800 miles.
To express this distance in scientific notation, we move the decimal point to the right until there is only one digit to the left of the decimal. This will result in a coefficient between 1 and 10. We then multiply this coefficient by 10 raised to a certain power.
In this case, we move the decimal point 13 places to the left, resulting in the coefficient 2.52657363328. Therefore, the distance of 4.3 light-years in miles, in scientific notation, is approximately 2.52657363328 x 10^13 miles.
