To determine
The words for which the letter LED stands for.
Expert Solution & Answer
Explanation of Solution
The LED stands for light emitting diode. They, are most common type of electrical device used.
The LED diode emits the light when they are forward biased and the electron in the N type of material combine with the holes in the p type material, in this way the energy is released in the form of photon lights.
The energy is released by the LED is in the form of the light as the holes and the electron recombine.
Thus, the LED stands for light emitting diode.

Draw the moment (M), axial (N), and shear (S) diagrams. Please note that this is a 3D problem and you will have moment (M) and shear (S) along two different axes. That means that you will have a total of 5 diagrams.arrow_forward
- I tried solving this one but have no idea where I went wrong can you please help me out with this?arrow_forwardQuestion 1. A tube rotates in the horizontal xy plane with a constant angular velocity w about the z-axis. A particle of mass m is released from a radial distance R when the tube is in the position shown. This problem is based on problem 3.2 in the text. y ω R m 2R Figure 1 X a) Draw a free body diagram of the particle if the tube is frictionless. b) Draw a free body diagram of the particle if the coefficient of friction between the sides of the tube and the particle is μs = flk = fl. c) For the case where the tube is frictionless, what is the radial speed at which the particle leaves the tube? d) For the case where there is friction, derive a differential equation that would allow you to solve for the radius of the particle as a function of time. I'm only looking for the differential equation. DO NOT solve it. e) If there is no friction, what is the angle of the tube when the particle exits? • Hint: You may need to solve a differential equation for the last part.
