Jasmine is a cook, and she wants to buy new equipment. she is presented with dishes made of copper, clay, plastic, and glass. she selects the copper pot because she does most of her cooking on the stove. which explains why she most likely chose copper? 1.copper is shiny and reflects light, which will cook the food. 2.copper is malleable and can be manipulated to cook food. 3.copper is ductile and can be stretched to cook the food. 4.copper is conductive and will absorb heat to cook the food.

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
