Anozzle is designed to accelerate the fluid from v1 to v2 in a linear fashion. that is, v = ax + b, where a and b are constants. if the flow is constant with v1 = 10 m/s at x1 = 0 and v2 = 25 m/s at x2 = 1 m, determine (a) the local acceleration; (b) the acceleration magnitude of the fluid at point (1); (c) the acceleration magnitude of the fluid at point (2).

Panel bc in fig. p2.76 is semi-circular, with the 3 meter radius and horizontal straight edge through point b. compute (a) the hydrostatic force of the water on the panel, (b) its center of pressure, and (c) the moment of this force about point b. assume atmospheric pressure on the dry side of the panel

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
