What is the difference between thermoplastic and thermoset plastic? Thermosoftening (also called thermoplastics) are plastics which will soften when heated and can be reshaped. Thermosetting plastics are plastics do not soften on heating. Can thermosetting plastics be reshaped? Heat-cured plastics called thermosets can’t be beat for their long lives. But these resilient polymers, used to […]

How many collisions are there in a crash? three collisions What are the 3 collisions in a crash? Motor vehicle crash involves three types of collisions: vehicle collision, human collision, and internal collision. Being aware of the three collisions and understanding the dangers allows occupants to understand where and how their injuries occur. What is […]

What is VOC in solar cell? Modules short circuit current (ISC) and the open circuit voltage (VOC) are fundamental figures in the design of solar systems. The Voc is determining the maximum string length (number of modules in one string), and Isc is required for calculating the maximum current in the string. How do you […]

What is the 5th term in the Fibonacci sequence? It is that simple! Here is a longer list: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811. What are the first 20 Fibonacci numbers? The […]

How is passband gain calculated? As the value of resistor, R2 divided by resistor, R1 gives a value of one. Then, resistor R1 must be equal to resistor R2, since the pass band gain, AF = 2….Active High Pass Filter Example No1. Frequency, ƒ ( Hz ) Voltage Gain ( Vo / Vin ) Gain, […]

What is the use of superposition principle? The superposition principle states that when two or more waves overlap in space, the resultant disturbance is equal to the algebraic sum of the individual disturbances. (This is sometimes violated for large disturbances; see below Nonlinear interactions.) What is an example of superposition? Use superposition to find the […]

How many possible keys are there for a Playfair cipher? 25 letters What is the size of the key domain in Playfair cipher? Playfair Cipher The key table is a 5×5 grid of alphabets that acts as the key for encrypting the plaintext. Each of the 25 alphabets must be unique and one letter of […]

How do you calculate ADC voltage? ADC has a resolution of one part in 4,096, where 212 = 4,096. Thus, a 12-bit ADC with a maximum input of 10 VDC can resolve the measurement into 10 VDC/4096 = 0.00244 VDC = 2.44 mV. Similarly, for the same 0 to 10 VDC range, a 16-bit ADC […]

Does fuel cell produce electricity? Fuel cells work like batteries, but they do not run down or need recharging. They produce electricity and heat as long as fuel is supplied. A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte. What is the reaction in […]

Where do you put commas? Use a comma after a dependent clause that starts a sentence. A dependent clause is a grammatical unit that contains both subject and verb but cannot stand on its own, like “When I went running …” Commas always follow these clauses at the start of a sentence. How do you […]
