Cut in voltage?
The forward voltage at which the current through the junction starts increasing rapidly, is called the knee voltage or cut-in voltage.
What is the behavior of a forward and reverse biased diode?
Forward Resistance:def: It is resistance offered by diode to the forward bias is known as forward resistance.This resistance is not the same for the flow of DC as for the changing current. Accordingly this resistance is of two types :1. DC FORWARD RESISTANCE.2. AC FORWARD RESISTANCE.1. DC forward resistance: It is the opposition by diode to the DC. It is measured by the ratio of DC voltages across the diode to the resulting DC current through it.2. AC forward resistance: It is the opposition offered by the diode to the changing current. It is measured by the ratio of change in voltage across diodes to the resulting change in current through diode. The AC forward resistance is more significant as the diodes are generally used with alternating voltage.Reverse Resistance:def: The resistance offered by the diode to the reverse bias is known as Reverse Resistance. It can be DC reverse resistance or AC reverse resistance depending upon whether the reverse bias is direct or changing voltage. Idealy the reverse resistance of a diode is infinte however in practice the reverse resistance is not infinite because for any value of reverse bias, there does exist a small leakage current. It may be emphasized their that reverse resistance is very large compared to the forward resistance.These Definitions are from PRINCIPLES OF ELECTRONICS by V.K MEHTA and ROHIT MEHTA
How do you invent the time-machine?
You don't. Time was created to be travled through in a forward progressing pattern, therefore if you try to reverse the process, you would fin that it would be an impossible process. In effect, your true answer would be: You can't.
What is the function of the propeller?
The propellers purpose is to pull (or push) the aircraft forward through the air. It does this in much the same way that the airplanes wing produces lift, only instead of being pushed forward through the air, it is spun in circles through the air.Most modern airplanes have a variable-pitch (fixed speed) propeller. The pilot is able to adjust the pitch (or bite) of the propeller to maximize performance at various altitudes.A propeller is a type of fan that converts rotational motion into thrust by transmitting power. The shape and angle of the blade create pressure.
How do you forward ports on routers and when and why?
To forward ports on your router just login to your router's on-line interface. Port Fowarding is used when a program (lets use FileFind [not a real program]) requests a port the router doesn't understand. Lets say that FileFind requests port 130 on your router, but your router doesn't have a port 130. It does, however, have a 128. The port forwarding tells the request to port 130 to be routed through port 128.
A rocket engine obtains forward momentum through the use of fuel additives?
fandango additives usually which contain oxygen
What happen to a vehicle's momentum when it crashes into a wall?
Momentum is transferred to the wall... And through it, to planet Earth.

absorption, photosynthesis
What role does gravity play in propelling an airplane through the air?
There are four forces acting on an airplane when it is in the sky: lift, gravity, momentum and drag. The lift makes the plane go up, gravity acts against it. The momentum of the plane makes it go forward, drag makes it go slower. Thus, gravity doesn't really even have to do with moving the plane forward.
What is the process through which the plant obtains energy from sunlight called?
Photosynthesis
What kind of food additives are those which become part of the food product through a circuitous route?
You might be trying to define 'incidental food additives'. or indirect food additives
Conservation of linear momentum and energy?
energy transfer through transferring momentum. karim khan

How does a democratic leader obtain power?
He obtains power through the people and the constitution.
Why a photon cannot rest?
A photon pass through different media at different speed, but that speed always is the highest speed it can achieve at those circumstances. That is because a photon's existence not depend on its structural energy to keep its structure stable but depend on its momenta energy to keep its existence in a dynamic balanced state --- just like an acrobat riding on a single wheeled bike --- he has to swing back and forth to stay on the seat. If you are structurally complex enough, for instances, got four leg like a chair, you can stand on them still; but if you only got one leg, standing still is not the way to keep you upright --- you have to swing back and forth to achieve that. Or you can speed forward all the way or spin. In the case of a photon, it does all three of these movements --- speed forward all the way and vibrate up and down and spins. That is what happening in the photon ---it doesn't have the structural complexity to keep its existence but have to depend on a combination of its momenta energy to achieve that. The forward momentum give it the inertial energy to keep its basic structure and the vibration momentum keeps this structure dynamically stable, the spin momentum keeps the electric field and magnetic field alternatively oscillating to keep a dynamically balanced fields state. There is a dynamically balanced equilibrium point between these momenta forces, before that point is reached, the energy distribution in the photon will only keep going one way --- flow to the lower potential direction. And that direction is the forward speed momentum which not reached the saturated point. Only at that balanced point, the energy distribution becomes two way adjustment mechanism --- if the forward speed not reached the maximum (actually it is the forward momentum not reached the maximum) at that circumstances, vibration energy will be converted into forward momentum; when an outside force give an extra forward momentum, that extra momentum energy will be converted into vibration momentum. That mechanism keeps the forward momentum constant --- note: it keeps the forward momentum constant but not the speed constant, the speed constant is the result of the constant forward momentum. That is the reason when light pass through different media have different speed --- under a constant momentum, it can only achieve different speed at different resistance. In vacuum space there is no resistance so the speed can keep c --- a constant. All these strange behaviour of a photon is decided by its unique character feature --- it is the smallest unit of energy and mass that can stably exist. It doesn't have structural energy to keep its very minimal structure in a thermodynamically stable state but it has to depend on its momenta energy to do so. That is the reason it behaves different from other bigger things --- its thermodynamically stable state is always at a constant speed (result from its constant forward momentum) while other bigger things will achieve a thermodynamically more stable state by losing its momentum energy and slow down.
