A total of 3.00 106 electrons are placed on an initially uncharged wire of length 1.44 m.
(a) What is the magnitude of the electric field a perpendicular distance of 0.412 m away from the midpoint of the wire?
(b) What is the magnitude of the acceleration of a proton placed at that point in space?
(c) In which direction does the electric field force point in this case?
1. The force points towards the wire.2. The force points away from the wire

Using DC Operating point analysis in Multisim (DO NOT USE MULTIMETER INSTRUMENT-NO CREDIT) determine the emitter voltage and emitter current. Provide a screenshot of the results window.
An attractive fuel for nuclear fusion is deuterium H 1 2 which constitutes about .015% of the hydrogen in the oceans If each deuterium nucleus produces 7.4 MeV in a fusion reaction, how much energy would be released if each H 1 2 atoms in the 4 gram..
An amplitude modulated amplifier has a radio frequency output of 50w at 100% modulation. The internal loss in the modulator is low. What output power is required from the modulator.
An alarm is powered by 120 VAC, and the on/off state of the alarm is controlled by an EM relay. Design the interface between a computer output port and the EM relay. The dropout voltage is 3.5 V, and the coil current needs at least 100 mA. Limit t..
During an all-night cram session, a student heats up a 0.491 liter (0.491 x 10- 3 m3) glass (Pyrex) beaker of cold coffee. Initially, the temperature is 19.7 °C, and the beaker is filled to the brim.
