A 13,000N car is driving down the road while the engine is applying a force of 4,000 N to the east. The friction acting on the car is 18,000 N. a) Draw the free body diagram.

b) Calculate the net force in the x and y directions.

c) Is the car accelerating? If yes, what direction is the acceleration vector pointing?

Describe cytokinesis in plants and animals. in animals: in plants.

Two 2.0-cm-diameter disks face each other, 1.0 mm apart. they are charged to ±10 nc. what is the electric field strength between the disks? a proton is shot from the negative disk toward the positive disk. what launch speed must the proton have to just barely reach the positive disk?

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
