An object moves along a distance MN. The first half of the block moves with a speed v1 = 30km/h. The second half of the way the object moves in two stages: in the first half, the object travels with a speed v2 = 20km/h, the second half goes at a speed v3 = 10km/h. Calculate the average speed of the object over the whole distance MN.

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
