What are the uses of alloys in daily life and how are alloys made?
Every metal thing you use in your daily life is made from an alloy. Alloying metals can make a metal that exactly meets your needs - if you need a metal that melts at 100 degrees C, or one that's harder than granite, alloying will let you fill your requirements.
Making an alloy is a three-step procedure. Metallurgists and engineers will determine the need for a new metal, its characteristics, and the mixture of base metals that will meet the requirements of the new metal in the most economical manner. Next, they will make a small batch of the alloy in a laboratory and test it to see if it works the way they want. If it does, they'll go to a metal plant and make a large batch to see if it works like it did from the small batch.

What are some nonmilitary uses for radar besides weather?
Radar can be used to detect distance to an object by determining round trip echo time. Some uses below:
Level monitoring of substances in a container or silo-the radar antenna transmits downward from the top of the container and determines the distance to the top of the substance, allowing the operator to determine the amount of substance in the tank.
Radar can be used by vehicle collision avoidance systems.
Basically, any time distance to an object is required, radar is an excellent solution.
How many minimum number of nand gates are required to realize xor gates?
As such an OR gate should do the job...but if the question is of using gates other than the simple OR, it should be a combo of NOR and NOT gates; where-in, the NOT gate comes after the NOR gate.
Factfully speaking:
The output of a NOR gate when fed to a NOT gate shall give you an OR gate.
cheers :)

How do you make a nand gate using xor gate?
XORing X with 1 gives X', i.e., NOT(X). If we are able to construct a NAND (AND) using XOR, we can also obtain AND (NAND) from it, which makes XOR a universal gate since inverted inputs to a NAND (AND) will give OR (NOR). However XOR is not a universal gate! Therefore we cannot obtain NAND (AND) using XOR. :-)

What is the fullform of PIC controller?
PICs are microcontrollers made by Microchip, Inc. PIC microcontrollers are used mostly in embedded control applications. Microchip offers hundreds of different PIC devices from tiny 6 pin packages up to 121 pin devices. The PIC line is offered in several families, based on an 8 -bit, 16-bit, or 32-bit core processor with various sets of peripheral and interface hardware on the chip. Each PIC has a processor, program memory, data memory, on board clock circuitry, timers and inputs and outputs.
Depending on the device chosen, the memory, operating speed and I/O capacity will vary. Additional functions may include A-D converters, serial ports, USB ports, external memory access, pulse width modulation, Ethernet ports, comparators, voltage references and more.
Because of the small instruction set and free assembler, PIC programmers often use assembly language to write programming. Although some higher-level language tools are available, languages like C are difficult to implement on some PIC devices because of hardware limitations, like a small fixed stack memory.
A vast amount of application and technical data is offered by Microchip. See the website at the link below.

How do you do staircase wiring?
A two way switch is required for staircase wiring. A staircase switch will have two terminals. Connect the line wire with the center terminal. Connect the two ends of a wire with the top two terminals and two ends of a wire with the bottom two terminals. The line wire at the center terminal can now be connected with one terminal of the light bulb or light holder.
Transfer function of stepper motor?
A stepper motor has a transfer function. The exact function is determined by a motor's individual characteristics. The speed at which it is capable of repeating a position is based on its geometric configuration and size.

18. Component Description and application
Relay Relays are a special type of switch which is turned on and off by an electromagnet. When a current flows through the coil an electro-magnetic field is set up. The field attracts an iron armature, whose other end pushes the contacts together, completing the circuit. When the current is switched off, the contacts open again, switching the circuit off.
A useful property of relays is that the circuit powering the coil is completely separate from the circuit switched on by the relay. For this reason relays are often used where a safe low-voltage circuit is being used to control a high-voltage circuit.
Contactor A contactor is an electrically controlled switch used for switching a power circuit. A contactor is activated by a control input which is a lower voltage / current than that which the contactor is switching. Unlike general-purpose relays, contactors are designed to be directly connected to high-current load devices, not other control devices
Capacitor Capacitors store and discharge electrical current. They're made from 2 parallel metal plates separated by an insulator (dielectric) applications include;
Smoothing rectified alternating current voltages into steady direct current voltages
Blocking direct current signals whilst allowing alternating signals to pass
Filtering out unwanted portions of a fluctuating signal
Timing applications
Storing charge to keep a transistor turned on or off
Sensor A sensor is a type of transducer. There is a massive range of sensors Direct-indicating sensors, for example, a mercury thermometer, are human-readable. Other sensors, such as thermocouples, only produce an output voltage or other electrical output which must be interpreted by another device (such as a computer).
Resistor Resistors resist or 'slow down' the current in a circuit by acting against the flow of electrons.
hope this helps your NVQ work
Why don't ceramic capacitors have positive and negative terminals?
Normal Case:
Normally one will not find a polarity associated with a capacitor. Indeed, the quality of the manufacture would be put into question is the capacitor functions differently with different sign for the applied voltage.
Abnormal Case:
While common resistors are expected to function independent of polarity, it is possible to create resistors which are nonlinear and nonsymmetric in response to applied voltage. Just as diodes are nonsymmetric, one can imagine a diode-like material incorporated into the material of the capacity. There is no clear application for a nonsymmetric capacitor.
The only reason to label a capacitor as preferring one side positive over the other might be the effect of the rate of discharge is one of the charged surfaces is exposed to an environment which preferentially picks up or loses charge and there by affects performance.
