MY NOTES ASK YOUR TEACHER Kepler's Third Law of planetary motion states that the square of the period 7 of a planet (the time it takes for the planet to make a complete revolution about the sun) is directly proportional to the cube of its average distance d from the sun. (a) Express Kepler's Third Law as an equation. (Use k for the constant of proportionality.) (b) Find the constant of proportionality by using the fact that for our planet the period is about 365 days and the average distance is about 93 million miles. (Enter your answers in scientific notation and round the decimal value to two decimal places) K = x 10 (c) The planet Neptune is about 2.79 x 109 mi from the sun. Find the period of Neptune.
