How much charge is on a segment ds ? Express your answer in terms of some, all, or none of the variables Q , a , θ , dθ , and the constant π .

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.

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

The slope of a velocity time graph over any interval of time gives the during that interval
