Do chickens fly yes or no? Chickens can fly (just not very far). Depending on the breed, chickens will reach heights of about 10 feet and can span distances of just forty or fifty feet. The longest recorded flight of a modern chicken lasted 13 seconds for a distance of just over three hundred feet. […]
What is material degradation?
What is material degradation? Degradation of Materials Degradation is the deterioration of a material as a result of a reaction with its environment. • All materials degrade at the surface to varying degrees when they are exposed to: • Sunshine (UV light) • Liquids (water, solution, oils) • Oxygen gas • Metals. How do materials […]
What happens in a parallel circuit with three bulbs?
What happens in a parallel circuit with three bulbs? When the bulbs are connected in parallel, each bulb has 120 V across it, each draws 1/3 A, and each dissipates 40 watts. Since all three bulbs are 40-watt bulbs, they have the same resistance, so the voltage drop across each one is the same and […]
What happens if you cut through an electric cable?
What happens if you cut through an electric cable? Cutting the live wire could result in a high voltage discharge, which can be harmful to you or equipment on the circuit. What you’re doing when you cut a live wire is exactly what a switch does, but a switch’s housing is grounded (earth), and well […]
When creating a weighted scoring model How do you identify criteria important to the project selection process?
When creating a weighted scoring model How do you identify criteria important to the project selection process? Steps in identifying a weighted scoring model: Identify criteria important to the project selection process. Assign weights (percentages) to each criterion so they add up to 100 percent. Assign scores to each criterion for each project. Multiply the […]
What is Level 1 and Level 2 cache?
What is Level 1 and Level 2 cache? L1 is “level-1” cache memory, usually built onto the microprocessor chip itself. For example, the Intel MMX microprocessor comes with 32 thousand bytes of L1. L2 (that is, level-2) cache memory is on a separate chip (possibly on an expansion card) that can be accessed more quickly […]
What is the differential approach?
What is the differential approach? Approach to study of behaviour that focuses on individual differences, abilities, and predictions. From: differential approach in The Oxford Dictionary of Sports Science & Medicine » Which method is used in fluid mechanics? Eulerian approach Which method is most commonly used in fluid mechanics for analysis? Eulerian method Why do […]
What is the use of FFT analysis?
What is the use of FFT analysis? The “Fast Fourier Transform” (FFT) is an important measurement method in the science of audio and acoustics measurement. It converts a signal into individual spectral components and thereby provides frequency information about the signal. How does an accelerometer measure vibration? How do you measure vibration? Vibration is most […]
What is the difference between threshold and resolution?
What is the difference between threshold and resolution? The difference between threshold and the resolution of the measuring instrument could be understood this way. Threshold defines the smallest measureable input, while the resolution defines the smallest measureable input change. What is the difference between resolution and sensitivity? RESOLUTION – the smallest portion of the signal […]
Does a still object have kinetic energy?
Does a still object have kinetic energy? Without speed, there’s no kinetic energy. However, to an observer moving with the object, the object will not appear to have kinetic energy. Can an object have both potential and kinetic energy? Potential energy is the energy stored in an object due to its position. Objects can have […]
