Inference Practice Q1/Euphorbia esula (leafy spurge) is a Eurasian plant that has become invasive in North America, where it displaces native vegetation and sickens cattle. E. esula can be controlled with chemical herbicides, but that approach can also kill harmless plants nearby. Recent research on introducing engineered DNA into plant species to inhibit their reproduction may offer a path toward exclusively targeting E. esula, consequently Which choice most logically completes the text? A. Making individual E. esula plants more susceptible to existing chemical herbicides. B. Enhancing the ecological benefits of E. esula in North America. C. Enabling cattle to consume E. esula without becoming sick. D. reducing invasive E. esula numbers without harming other organisms

Triangle (Algorithm) Area of a triangle is defined by 0.5 * Base * Height. Write the algorithm to input Base and Height, then calculate and output the area of a triangle. Write the requirement analysis (input and output) and the algorithm in the answer box. For example, if the base is 4 and height is 5 then the area will be 10. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).

1. (13 pts) The heat transfer coefficient for a fluid flowing through a copper tube (2.5 cm outside diameter with 3.0 mm wall thickness) is 1.2 kW/(m²K). The heat transfer coefficient for another fluid outside the tube is estimated to be 4.0 kW/(m²K). The average temperatures of the inside fluid and outside fluid are 60°C and 10°C, respectively. Use $k_{cu} = 400$ W/(m·K). Calculate a) the overall heat transfer coefficient based on inside tube area, (6 pts) b) the rate of heat transfer per unit tube length, (3 pts) and c) the inside and outside tube-wall (surface) temperatures (4 pts)
