Air (1 atm, 5°c) with free stream velocity of 4 m/s flowing in parallel to a stationary thin 1 m × 1 m flat plate over the top and bottom surfaces. the flat plate has a uniform surface temperature of 35°c. if the friction force asserted on the flat plate is 0.1 n, determine the rate of heat transfer from the plate.\

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f

Object a has a length of 3 cm, a width of 2 cm, and a height of 4 cm. object b is dropped into a graduated cylinder. it displaces 19 ml of water. the volume of object a is: a: greater than the volume of object b b: less than the volume of object b c: equal to the volume of object b
