3. To measure the drag of an upright person, without violating human-subject protocols, a life- sized mannequin is attached to the end of a 6-m rod and rotated at ?-80 rev/min, as shown in the figure. The power required to maintain the rotation is 60 kW. By including rod-drag power, which is significant, estimate the drag-area CDA of the mannequin, in m.

i have some physics questions. please answer all. 1.Consider a V = 0.80-m3 open container made out of thin metal sheets with a linear expansion coefficientα = 193 × 10-6-°C-1. The container is filled to the brim with a liquid whose volume expansion coefficient isβ = 33 × 10-6-°C-1. The container and liquid are initially at a temperature of Tini = 90-°C, but are allowed to cool down to Tfin = 7.3-°C. How much of the liquid spills over as...

Allen's hummingbird (Selasphorus sasin) has been studied by zoologist Bill Alther.† Suppose a small group of 18 Allen's hummingbirds has been under study in Arizona. The average weight for these birds is x = 3.15 grams. Based on previous studies, we can assume that the weights of Allen's hummingbirds have a normal distribution, with σ = 0.36 gram. (a) Find an 80% confidence interval for the average weights of Allen's hummingbirds in the study region. What is the margin of...
