An engineer is designing a process for a new transistor. she uses a vacuum chamber to bombard a thin layer of silicon with ions of phosphorus, each of mass mp = 5.18 × 10-26 kg. the phosphorus ions are doubly ionized, with each phosphorus ion lacking two electrons. the ions start at rest at one end of the vacuum chamber and are accelerated by an electric field over a distance of re = 46 cm before they strike the silicon layer with velocity vp = 180 m/s. calcultae the average electric field strength, e, across the vacum chamber.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
