What is the trace on an oscilloscope? Photo: An oscilloscope draws a trace (graph) of some quantity (plotted on the y-axis) that varies with time (plotted on the x-axis). One common pattern you’ll see is this smoothly undulating, snake-like up-and-down trace, which is called a sine wave or sinusoidal wave (green upper line). What is […]
How do you create a weighted scoring model?
How do you create a weighted scoring model? How to create and use a weighted scoring model Step 1: List out your options. This is the easiest step in the process. Step 2: Brainstorm your criteria. Step 3: Assign weight values to your criteria. Step 4: Create your weighted scoring chart. What is a weighted […]
How does heat conduction differ from heat convection?
How does heat conduction differ from heat convection? In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. In radiation, heat transfer occurs through electromagnetic waves without involving particles. What is the difference between conductive heat transfer and convective heat transfer give one example of […]

Why is BOD test done for 5 days?
Why is BOD test done for 5 days? The standard oxidation (or incubation) test period for BOD is 5 days at 20 degrees Celsius (°C) (BOD5). The BOD5 value has been used and reported for many applications, most commonly to indicate the effects of sewage and other organic wastes on dissolved oxygen in surface waters […]
What depth are TYRE wear indicators set at?
What depth are TYRE wear indicators set at? 1.6mm Where is the tire wear indicator? Tread wear indicators (“wear bars”) are located at the base of the main grooves and are equally spaced around the tire. The tread wear indicators, which look like narrow strips of smooth rubber across the tread, will appear on the […]
How do you calculate equivalent sound level?
How do you calculate equivalent sound level? The equation to calculate Leq divides the integrated, normalized sound pressure by the duration of interest of the signal. The result is expressed in units of decibels: Leq = equivalent continuous sound pressure level in dB. How do you calculate sound pressure level? Sound pressure level (SPL) is […]
What is better to have torque or horsepower?
What is better to have torque or horsepower? Torque, simply, is the ability of a vehicle to perform work — specifically, the twisting force applied by the crankshaft. Horsepower is how rapidly the vehicle can perform that work. Because there is generally a limit on how fast you can spin an engine, having higher torque […]
