Most workers in nanotechnology are actively monitored for excess static charge buildup. The human body acts like an insulator as one walks across a carpet, collecting-50 nC per step. What charge buildup will a worker in a manufacturing plant accumulate if she walks 31 steps? charge buildup from 31 steps: How many electrons are present in that amount of charge? electrons present: nC maximum number of steps: electrons If a delicate manufacturing process can be damaged by an electrical discharge greater than 1012 electrons, what is the maximum number of complete steps that any worker should be allowed to take before touching the components? steps

A rubber rod is rubbed with a piece of fur and, as a result, the rubber rod has a negative charge. What happened? O Protons were removed from the rod. O The fur became negatively charged. O Electrons were added to the rod. O The fur was left neutral.

A 6 g ball with a charge of 4 μC hangs by a thread between two oppositely charged parallel plates as shown below. The distance between the ball & the edges of the plates is much greater than the distance between the plates. Each plate has the same constant uniform charge density. A + 30° Determine the voltage between the plates. -61.9806 V X 67.8963916567 V Determine the polarity of each plate. You will not receive credit until you have correctly selected the polarities of both plates. left plate neutral right plate impossible to determine 8 mm ×

you have been given some info, use it to solve the questions highlighted in yellow. - an alpha particle has charge 2e and mass 6.64x10^(-27). - The alpa particle is shot aimed at a gold nucleus which is stationary. The gold nucleus has a charge of 79e. - Then the gold nucleus and the alpha particle are 10cm appart from eachother, the alpha particle moves at 1000m/s. a. What is the speed of the alpha particle when it is 1.00mm away from the gold nucleus? b. What is the closest distance the alpha particle can go reletive to the gold nucleus before the alpha particle rebounds ?
