Carrier Definition and 127 Threads

The Carrier of an Emf is in many definite/indefinite parts the net of the circuits Total Resistance (Rt). These definite/Indefinite parts are the SMALLEST degree expressed to that of a single atom, the basic Resistive properties or qualities of Itself, and the electron structure as pertaining to...

Back on lecture about Standard model, professor said that original Weinberg-Salam-Glashow theory had to be augmented with Higgs mechanism because it didnt give rise to massive gauge fields, yet since weak interaction had finite range they knew it had to have a massive carrier, well three of them...

Dear All I will be grateful for any idea on how to measure electrochemically the charge carrier in an electrode say working electrode made of Al. Thank you from advance Shay

I've been searching for an acceptable value for the charge density of indium arsenide; that is, the amount of charge per cubic meter. I have been unable to find anything. I'm working on a replication of the Hall Effect, and I need an accepted value for comparing my own results. I've searched...

I'm reading Feynman's book QED, and while I'll need at least another couple of read-throughs to grasp what I can, there are already a few fundamental questions I have. Feynman explains that electrons and protons within an atom exchange photons (p. 113 of my copy). I'm interpreting this as the...

Hello everyone. Right now I'm learning about carbon electrical properties for my final assignment in college. But somehow i just can't find the intrinsic carrier concentration properties for carbon. I've found the graphics that show me the relationship between the intrinsic carrier...

i designed an crystal oscillator of 1MHz using MC14069 ic and now i need the design of a power amplifier circuit to increase the power of the 1MHz carrier wave...can somebody help me with this!

Homework Statement The Attempt at a Solution Vch = Vce + Vhe Do I have this correct? I am guessing I need to find the velocity of the carrier with the respect to earth, and also find the velocity of the helicopter with respect to earth. Than with these two answers I can find...

Can any please help me in solving the following two questions Q1 A Si sample is doped with 10^16 per cm cube boron atoms and a certain number of shallow donors. The fermi level (Ef) is 0.36 eV above Ei (intrinsic energy level) at 300K. What is the donor concentration Nd? For Si at 300K...

need help.. carrier 5 miles N of sub traveling E @ 3mins/hr. sub has torpedoe travel @ 40 knots. what is the angle and distance travel of torpedoe to hit carrier, what is travel time . with respect to original sighting

Homework Statement Given "n=Nc*e-(Ec-Ef)/KT", prove "n=ni*e(Ef-Efi)/KT" Homework Equations Quasi-Fermi Energies..? Ef is Fermi level (extrinsic) and Efi is Fermi level (intrinsic). Ec is Fermi level (conduction). The Attempt at a Solution Very honestly, I cannot figure out how to...

Homework Statement Submarine is traveling at 12 m/s toward an aircraft carrier emits a 2400 Hz sonar pulse. The reflected pulse returns with a frequency 2310 Hz. What is the speed of the aircraft carrier? (Positive/negative means the carrier is moving toward/away from the submarine.) The...

Just read the title. That's all I want to know.

A plane weighing 220 kN (25 tons) lands on an aircraft carrier. The plane is moving horizontally at 63 m/s (141 mi/h) when its tailhook grabs hold of the arresting cables. The cables bring the plane to a stop in a distance of 89 m. (a) How much work is done on the plane by the arresting...

Good Day, Can some one tell me any reading about structure of voice? Things I need to know (in AM radio) amplitude madulation of voice and also demodulation of it. When we demodulate it do we use some carrier frequency to so people can hear that? Thanks

Does anyone know what kind of time it takes for an aircraft carrie to reach full speed if it starts from rest? Specifically a nuclear powered US carrier (nimitz maybe?). Someone said it takes 5 hours and I am just having a hard time believing it.

Thus far in part II of the book, we have reconsidered the metaphysics of causation, rejecting notions of causal responsibility as the core explanatory target of a theory of causation and constructing a richer and more objective Theory of Causal Significance. With a new theory of causation in...

I've been trying to find a formula for calculating charge carrier density of a material, or a table of values , but can't seem to find any. If anyone knows of a link to a formula or table, any help would be welcome. Thanks, Plas

Hello, I am having a bit of trouble with the following problem: Assuming a built in voltage equal to the bandgap voltage, calculate the slowest possible transmit time for a carrier with 5V reverse bias applied to the GaAs photodiode. I would be able to do this problem without difficulty if...

To my embarrassment I realized I do not understand this. How does a photon mediate the EM force? If I put two magnets close to each other then there is no EM radiation jumping from the one to the other. So how does the photon carry the particle? I know that very magnet has a Magnetic field...

An end of chapter question that i don't really know how to do.. Question: A copper connecting wire has a cross-sectional area of 3mm^2 and is 30cm long. (A) Estimate the amount of free charge in this wire. (B) How long will it take for all this free charge to pass through the wire when a...

Photon doesn't interact with external force and move with light speed. But why can it act as force carrier, play a role in photoelectric etc.?

How do you observe a carrier particle? How do you know that particles carry the strong force or weak force?

heres the problem: steam-powered catapult used to launch aircraft could "throw a nissan pick-up five miles(8045meters)" catapult has the power to accelerate 30-ton aircraft from zero to 160mph(71.511m/s) in just 2.5 seconds nissan pick up truck weighs 3500 pounds and the flight deck is 57...

A discussion came to surface in my Biology II AP class about heredity and sex linked characteristics. Now with a female carrying two X gametes and a male containing an X and Y gamete, males are more prone to inherit sex linked characteristics such as red-green color blindness and hemophilia. The...

Hi folks, quick question, i have just read a small snippet on data transfer that has sparked some thoughts. Basically it was this: Baseband transmission, one carrier frequency is used and the electrical signal is applied directly to the wires. Broadband transmission, signal is sent by...

I was wandering what area this would be called under Physics, however,The question is this... Considering that you have the ability to convert a text data or photo data into recognizable information to our brain, what would the possiblity be to transfer a 1,000 page textbook from a...
