The following equations represent the four parts (a, b, c, and d) of a cyclic process with a gas. the gas does not obey the ideal gas law. w is the work done by the system on the environment and consequently q−w=δuint. w=(3.0×105n/m2)(0.020m3−0.010m3)+0+ (1.0×105n/m2)(0.010m3−0.020m3)+0 δuint=(3/2)(1.0mole)(8.3j/mole⋅k)[( 700k−360k)+(480k−700k)+(240k−480k)+ (360k−240k)] q=qa+qb+qc+qd

During takeoff, the sound intensity level of a jet engine is 170db at a distance of 34 m. what's the sound intensity level at a distance of 1.0 km?

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.
