Astudent wants to demonstrate entropy using the songs on her portable music player. what should she do to demonstrate the lowest entropy? a. play a single song by a single artist b. play only the classical songs on shuffle c. play all the songs in alphabetical order d. play all the songs on shuffle

 A. play a single song by a single artist

Explanation: Entropy is the measure of randomness or disorder of a system.

A system that has more random distribution is considered to have more entropy and a system with ordered arrangement is considered to have less entropy.

Playing a single song by a single artist has least randomness , and lowest disorder and thus has lowest entropy.

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
