You are using a rope to lift a 14.5 kgkg crate of fruit. Initially you are lifting the crate at 0.500 m/sm/s. You then increase the tension in the rope to 180 NN and lift the crate an additional 1.15 mm. During this ddd motion, how much work is done on the crate by the tension force?

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
