A 200 kg set used in a play is stored in the loft above the stage. The rope holding the set passes up and over a pulley, then is tied backstage. The director tells a 100 kg stagehand to lower the set. When he unties the rope, the set falls and the unfortunate man is hoisted into the loft. What is the stagehand' acceleration? < Disregard this question and is an information for the question belowHow does the magnitude of the tension acting on the set change from when the rope was tied backstage to when the stagehand is being hoisted into the loft?A. The magnitude of the tension decreased B. The magnitude of the tension increased C. The magnitude of the tension is the same for both cases

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.
