Compute the electrical conductivity ((ωm)−1 ) of a cylindrical silicon specimen 5.1 mm in diameter and 51 mm in length in which a current of 0.1 a passes in an axial direction. a voltage of 12.5 v is measured across two probes that are separated by 38 mm.

Let f(x) = x4- 8x2 . find the relativeextrema of this function using the second derivative test.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
