Consider the analog signal x (t )equals 10 cos (100 pi t ), lets sample this signal with a sampling frequency of 75 Hz. Let's reconstruct this analog signal with the same sampling frequency. What is the frequency of reconstructed analog signal

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.
