Navon (1977) presented participants with big letters made up of smaller letters. He had some participants identify the large letter, while other participants had to identify the smaller letters. Finally, on some trials, the large and small letters conflicted (e.g., a large H made of small Ss) while on other trials, the large and small letters were consistent (a large H made up of small Hs). What did he findr?

(a). When a 0.80 kg crown is submerged in water, its apparent weight is measured to be 7.30 N. what is the density of the crown (take density of water to be 1,000kg/m3). (2.5 points) (b). The blood flow speed through an aorta with area 3.14 x 10-4 m2 is 0.265 m/s. If hardening of the arteries causes the aorta to be constricted to an area of 2.01 x 10-4 m2, what is the flow speed in the constricted area? (1.5 points)

(a). Three forces, F1 = 150 N, F2 = 10.0 N and F3 = 30.0 N act on a 15 kg object. If F1 and F2 act in same direction, while F3 acts in the opposite direction, what is the magnitude of the acceleration of the object? (2.5 points) b). To negotiate a curve of radius 38 m, the maximum force of static friction (centripetal force) that can act on a 1,350-kg car going around the curve is 8,200 N. What speed limit should be posted for the curve so that cars can negotiate safely? (3.0 points) c). With what speed must a 75 kg object be going to have a linear momentum of 925 kg m/s? (1.5 points)
