A heat source transfers 100 Btu/min to a metal surface for welding. The heated area is approximately circular, and the heat intensity decreases with an increasing radius as follows: 50% of the power is transferred within a circle of diameter = 0.2 in, and 75% is transferred within a concentric circle of diameter = 0.5 in. What are the power densities in (a) the 0.2-in diameter inner circle and (b) the 0.4-in diameter ring that lies around the inner circle?...
1. Let A be the surface area of a cube with side s at time t. a) If the side changes at a rate of 3.0 cm/min, at what rate is the cube's surface area changing when the side is 25 cm? b) If the side changes at a rate of -5.0 cm/min, what is the side of the cube when the surface area is changing at a rate of -240 cm2 /min? 2. Find dy/dx by differentiating implicitly. Express...
dit The rate at which a body cools also depends on its exposed surface area S. If Sis a constant, then a modification of (2) given in Section 3.1, dr kS(T-T). where k < and Te is a constant. Suppose that two cups A and Bare filled with coffee at the same time. Initially, the temperature of the coffee is 66* C. The exposed surface area of the coffee in cup is twice the surface area of the coffee in...
The height of a triangle is increasing at a rate of 2 cm/min while the area of the triangle is increasing at a rate of 5 square cm/min. At what rate is the base of the triangle changing when the height is 4 centimeters and the area is 6 square centimeters? Answer: 3 cm/min.
