Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?

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) ! : )

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.
