Three spiders are resting on the vertices of a triangular web. The sides of the triangular web have a length of a = 0.45 rn, as depicted in the gure. Two of the spiders (51 and 53) have +8.4 pl: charge, while the other (52) has 78.4 pC charge. 11/2 \\_ (a) What are the magnitude and direction of the net force on the third spider (S3)? magnitude y N direction g counterclockwise from the +X-axis (b) Suppose the third spider (53) moves to the origin. Would the net force on the third spider (S3) be greater than, less than, or equal to the magnitude found in part (a)? O greater than in part (a) 0 less than in part (a) 0 equal to the part (a) J (c) What are the magnitude and direction of the net force on the third spider (53) when it is resting at the origin? magnitude X How do you nd the magnitude of the electric force? How do you find the total net force? N direction w/ cdunterclockwise from the +X-axis A nozzle with a radius of 0.390 cm is attached to a garden hose with a radius of 0.850 cm. The ow rate through the hose is 0.340 Lfs. (Use 1.005 x 10'3 (N/mz) - 5 for the viscosity of water.) (a) Calculate the Reynolds number for ow in the hose. 25203.9 y (b) Calculate the Reynolds number for flow in the nozzle. 26,6298 X Can you modify the expression used in part (a) to determine Reynolds number for part (b)? (c) This flow is classified as which of the following? O turbulent O laminar O unstable v
