Precision can be defined as the a.) exact center of a data set. b.) reproducibility of a measured value. c.) correlation between two variables that are measured in a data set. d.) agreement between a measured value and an accepted value.

Oxygen undergoes an isentropic expansion from 120 degree c and 280 kpa absolute to 140 kpa absolute. determine the final temperature of the oxygen and the amount of work per kg of o_2 produced in the process if it is adiabatic.

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.

Which body part transports oxygen removes waste materials in carries nutrients to the body as part of the circulatory system
