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 out how much greater Earth's diameter is than Mars', you simply subtract the diameter of Mars from the diameter of Earth.
Diameter of Mars = 6.8 x 10^3 kilometers
Diameter of Earth = 1.2763 x 10^4 kilometers
Diameter of Earth - Diameter of Mars = (1.2763 x 10^4) - (6.8 x 10^3)
To subtract these values, we need to align the decimal places by adjusting the exponents:
= (1.2763 x 10^4) - (0.68 x 10^4) [dividing both sides by 10^3]
= 1.2763 x 10^4 - 0.68 x 10^4
= 0.5963 x 10^4 [combining like terms]
= 5.963 x 10^3
Therefore, Earth's diameter is about 5.963 x 10^3 kilometers greater than Mars' diameter.
The answer is a) 5.963 x 10^3 kilometers.
