Assume that earth has a circular orbit with a radius of 1 au. at its most favorable opposition mars is 0.37 au from earth, and at its least favorable opposition it is 0.68 au from earth. from these data, what do you calculate as the sidereal period of mars (in years)?

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
