As you wrote above, a dozen represents 12 items. You do not have enough items to make a dozen, so you decide to make a new counting unit with a number smaller than 12, called an OWL. As a class, what number would you like our OWL to represent?

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
