Final answer:
The period of revolution for a planet 16 AU from the sun, according to Kepler's 3rd Law, is 64 years.
Step-by-step explanation:
According to Kepler's 3rd Law, the orbital period (P) of a planet is proportional to the square root of the cube of its mean distance from the sun (a). To calculate the period of revolution, we can use the equation P = a^(1.5).
In this case, the mean distance from the sun is given as 16 Astronomical Units (AU). Therefore, we can substitute a = 16 into the equation and calculate:
P = 16^(1.5) = 64 years.
Therefore, the period of revolution for a planet 16 AU from the sun, according to Kepler's 3rd Law, is 64 years.
