The mass of the Earth is close to 5.97x10^24 kg and the mass of Venus is close to 4.87x10^24 kg. What is the approximate combined mass of both planets
A.1.08x10^25
B.2.91*10^49
C.1.08^10^48
D.1.08*10^25
I get 10.84 * 10^24 = 1.084 * 10^25
A and D are the same, except for the notation.
To find the approximate combined mass of both planets (Earth and Venus), you need to add their individual masses together.
Given:
Mass of Earth = 5.97x10^24 kg
Mass of Venus = 4.87x10^24 kg
To add these masses, we can simply add the numerical values and keep the same exponent:
Combined mass = (5.97x10^24) + (4.87x10^24)
Now, add the numerical values together:
Combined mass = 10.84x10^24
To express this in scientific notation, we need to adjust the number so that there is only one digit before the decimal point. Thus, we can write it as:
Combined mass = 1.084 x 10^25
So, the approximate combined mass of Earth and Venus is 1.084 x 10^25 kg.
Therefore, the correct answer is (D) 1.08x10^25.
