You launch a ball in the air with an initial velocity of 25 m/s. What is the acceleration going up ?
A. 9.81 m/s2
B. - 9.81 m/s2
C. 25 m/s

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.

The act of moving from one place to another. a. locomotor b. aerobic c. stationary d. static
