Compare the thermal velocity with the drift velocity of electrons in one mole of a divalent metal wire carrying 7 A at 40 K. The wire has a diameter of 1mm. With the numbers that you’ve calculated, describe the motion of the electrons in a few sentences.

What is drift velocity?

2. (a) The drift speed of electrons in a complete circuit, is typically a few mil- limeters per second. Yet, a lamp 3.0m away from a light switch turns on instantaneously when you flip the switch. Explain this apparent paradox. (b) To move charges in metallic wires, an internal electric field must exist in the wire. In such a wire, are the electric field and the electric current in the same or opposite directions? Explain.

One mole of acetyl chloride was mixed with one mole of dimethylamine.

One mole of acetyl chloride was mixed with one mole of dimethylamine. After the reaction is complete, what species can be found in the mixture? Draw only the organic structures (i.e., omit inorganic ions). Show charges where necessary.

a) In a Gunn diode oscillator, the electron drift velocity was found to be 107 cm/sec and the critical field for GaAs as 3.2 KV/cm. If the effective length is 20 microns, determine the i. Intrinsic frequency ii. Critical voltage that can be applied to the diode.

Please qualitatively describe drift velocity and why it opposes the relative motion of a conductor and a magnet.

Please qualitatively describe drift velocity and why it opposes the relative motion of a conductor and a magnet. Five to six sentences is enough.

Bob and 2 students of his drift by Dave at velocity vH in the x-direction. He then synchronizes all the clocks in his reference frame, using the perfect Einstein Convention. Bob has a flashlight. Dave is some distance away from Bob, observing. Consider two students, with t-shirts reading l and -l, along the x-axis of Bob, one in front, and one behind Bob. When Bob fires his light flash, which student receives the light flash first, as observed by Dave?...
