Hace 4 días · A relative frequency is the ratio (fraction or proportion) of the number of times a value of the data occurs in the set of all outcomes to the total number of outcomes. To find the relative frequencies, divide each frequency by the total number of students in the sample–in this case, 20.
Hace 5 días · The constituent frequencies are a discrete set of harmonics at frequencies ,, whose amplitude and phase are given by the analysis formula: c n = 1 P ∫ − P / 2 P / 2 f ( x ) e − i 2 π n P x d x . {\displaystyle c_{n}={\tfrac {1}{P}}\int _{-P/2}^{P/2}f(x)\,e^{-i2\pi {\frac {n}{P}}x}\,dx.}
Hace 4 días · The velocity of the shear wave in titanium is 3,018.5 m/s, which you can find by dividing the shear modulus, G = 41 GPa by density, ρ = 4,500 kg/m³ and then taking the square root. Use the shear wave velocity calculator to determine the velocity of a shear wave propagating in the body.
