What is a polymeric material? Image credit: Maksim) Polymers are materials made of long, repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded and how they are bonded. Some polymers bend and stretch, like rubber and polyester. Others are hard and tough, like epoxies and glass. What […]

In which filter the output and input voltage are equal in amplitude for all frequencies? all-pass filter What is the function of filter circuit? A filter is a circuit capable of passing (or amplifying) certain frequencies while attenuating other frequencies. Thus, a filter can extract important frequencies from signals that also contain undesirable or irrelevant […]

What occurs in an evaporator? The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the fan air flowing around […]

What are the components of hydrological cycle? The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation is the process of a liquid’s surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor. What are 4 main components of the […]

What is the difference between bending moment and shear force? Shear force is taken +ve if it produces a clockwise moment and it is taken -ve when it produces an anticlockwise moment. Bending Moment – Bending moment at any point along a loaded beam may be defined as the sum of the moments due to […]

What are drivers supposed to do when two or more vehicles arrive at a 4 way stop intersection at the same time? Yield to right. When two vehicles arrive at a 4-way stop at the same time, and are located side-by-side, the vehicle furthest to the right has the right of way. If three vehicles […]

How do you convert a floating point number to binary? Converting to Floating point Set the sign bit – if the number is positive, set the sign bit to 0. Divide your number into two sections – the whole number part and the fraction part. Convert to binary – convert the two numbers into binary […]

Which of the following is a stealth aircraft designed to be invisible to enemy radar? Reduced radar cross section is only one of five factors the designers addressed to create a truly stealthy design such as the F-22. The F-22 has also been designed to disguise its infrared emissions to make it harder to detect […]
