the diameter of mars is about 6.8 x 10^3m kilometers. The diameter of Earth is about 1.2763 x 10^4 kilometers. About how much greater is Earths diameter than the diameter of Mars? please answer in scientific notation.
a 5.963 x 10^3 kilometers
b 5.963 x 10^7 kilometers
c 59.63 x 10^3 kilometers
d 5.963 x 10^4 kilometers
To find the difference in diameters, we subtract the diameter of Mars from the diameter of Earth:
1.2763 x 10^4 kilometers - 6.8 x 10^3 kilometers
To subtract these numbers, we need to write them in the same unit. To do that, we convert the diameter of Mars to kilometers:
6.8 x 10^3 meters * 10^-3 kilometers/1 meter = 6.8 x 10^3 * 10^-3 = 6.8 kilometers
Now we can subtract the diameters:
1.2763 x 10^4 kilometers - 6.8 kilometers = 1.2753 x 10^4 kilometers
Therefore, the diameter of Earth is about 1.2753 x 10^4 kilometers greater than the diameter of Mars.
