What is domain ferromagnetism?

What is domain ferromagnetism? In ferromagnetic materials, smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. Their atomic makeup is such that smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. What is […]

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 […]

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 […]

How do you draw a spur gear?

How do you draw a spur gear? How to design a Spur Gear (with Equations) Adding Variables. Go to: Tools > Equations, then add these under Global Variables: Drawing the Gear’s outline. Draw a circle, then assign its diameter to “Head Diameter”. Adding a Bore (Optional) Extruding the Sketch (Base) Drawing the Gear’s teeth inbetweens. […]

What does cyanide do to the body?

What does cyanide do to the body? Cyanide prevents the cells of the body from using oxygen. When this happens, the cells die. Cyanide is more harmful to the heart and brain than to other organs because the heart and brain use a lot of oxygen. How many apple seeds will kill a human? Finally, […]

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 […]

What are the benefits of genetic engineering?

What are the benefits of genetic engineering? The possible benefits of genetic engineering include: More nutritious food. Tastier food. Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer) Less use of pesticides. Increased supply of food with reduced cost and longer shelf life. Faster growing plants and animals. What are […]

What is the process of honing?

What is the process of honing? Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive grinding stone or grinding wheel against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but can also improve the surface finish. […]
