For a steel alloy it has been determined that a carburizing heat treatment of 10.1 h duration will raise the carbon concentration to 0.38 wt% at a point 2.1 mm from the surface. estimate the time necessary to achieve the same concentration at a 6.5 mm position for an identical steel and at the same carburizing temperature.

Sarah and michelle work at a tech company that designs exercise apps. sarah tells michelle she has heard that james, their supervisor, interviewed with a competitor and may be leaving the company, which would open up a management position. what kind of power is sarah exerting?

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) ! : )
