Density in physics formula
WebWorked example: Calculating flux density A $15 \mathrm{~cm}$ length of wire is placed vertically and at right angles to a magnetic field. When a current of $3.0 \mathrm{~A}$ flows in the wire vertically upwards, a force of $0.04 \mathrm{~N}$ acts on it to the left. WebLinear density is the measure of a quantity of any characteristic value per unit of length. Linear mass density (titer in textile engineering, the amount of mass per unit length) and linear charge density (the amount of electric charge per unit length) are two common examples used in science and engineering.The term linear density is most often used …

Thus, the formula of energy density will be the sum of the energy density of electric and magnetic fields both together.
WebFeb 2, 2024 · Calculate the density of the substance with the ratio: ρ = m/V. Choose your reference substance and calculate its density: ρr = mr/Vr Calculate the ratio between the densities: sg =ρ/ρr. The answer is the specific gravity of the substance. Why do we use water as a reference when calculating the specific gravity? WebApr 5, 2024 · The formula of relative density or R. D = Density of Substance Density of Water R. D = ( ρ s u b s t a n c e) ( ρ r e f e r e n c e) Relative density is a dimensionless quantity. If a substance is said to have a relative density less than one then it is less dense compared to a reference substance.
WebCurrent densities are usually expressed in pA⋅pF −1 ( pico amperes per pico farad) (i.e., current divided by capacitance ). Techniques exist to empirically measure capacitance and surface area of cells, which enables calculation of current densities for different cells. This enables researchers to compare ionic currents in cells of different sizes. WebThe density of graphite is 2.266 g/cm 3 and the density of diamond is 3.51g/cm 3.
