The mass of an electron is of the order of 10^-30 kg and the mass of the universe is believed to be of the order of 10⁵² kg.From this information you can conclude that A)the mass of Earth is 52 orders of magnitude greater than that of the electron. B)the mass of Earth is 30 orders of magnitude greater than that of the electron. C)the mass of the electron is 82 orders of magnitude greater than that of Earth. D)the mass of Earth is 82 orders of magnitude greater than that of the electron. E)the mass of the electron is 30 orders of magnitude greater than that of Earth.

The difference in orders of magnitude between the mass of the electron and the mass of the universe is 152, which means the mass of the universe is 152 orders of magnitude greater than that of the electron. Therefore, the difference in orders of magnitude between the mass of the electron and the mass of Earth would be 152 - 30 = 122. This means that the mass of Earth is 122 orders of magnitude greater than that of the electron, which can be rounded to 82 orders of magnitude (since the option 82 orders of magnitude is closer to the actual value than option 122). Hence, choice D is correct.
