WebSep 12, 2024 · The speed of the waves on the strings, and the wavelength, determine the frequency of the sound produced. The strings on a guitar have different thickness but may be made of similar material. They have different linear densities, where the linear density is defined as the mass per length, (16.4.1) μ = mass of string length of string = m l. WebThe Given parameters are: Total Current, I = 5 mA Total Area, A = 15 mm² The Current density formula as, J = J = J=0.33 A/m² Thus current density is 0.33 A/m² Q.2: Determine the current density of 100 Amperes of current is flows through the battery in an area of 10 m² ? Solution Given parameters Current I = 100 A, Area, A = 10 m²
WebWell, just as we said the density is equal to quantity divided by area. If we multiply both sides of this equation by area you get area times density is going to be equal to quantity. And we know the density. It's 13 cats per square kilometer, and we can figure out the area and then just multiply the two. So what's the area of this right over here?
