A body starts from rest and travels ‘s’ m in 2nd second, than acceleration is. 1) 2s m / s2 2) 3 s m / s2 3) 23 s m / s2 4) 32 s m / s2

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.
