Quizplus · Accepted Answer

The acceleration due to gravity is inversely proportional to the square of the distance between two objects. Therefore, the acceleration due to the Sun's gravity on Pluto is (1/40)^2 = 1/1600 times the acceleration due to the Sun's gravity on Earth. The format of the answer should include the fraction in numerical form with the scientific notation.
