A black mumba, the world’s most poisonous snake sees a prey and begins slithering out toward it with a velocity of 18.0km/h. After 2.30s, the mumba realizes that its prey can move faster than it can. The snake then turns around and slowly returns to its hideout in 12.0 s. Calculate the mumba’s average velocity for the complete trip. the mumba’s average speed for the complete trip. Show Your Work

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
