What is the difference between accurate data and reproducible data?

Accuracy is a general concept while precision is more of a mathematical concept. On the whole though, the conceptual boundary between the use of the two words is kind of fuzzy. While accuracy means being correct and true in every detail, precision means being more exact and to the point in reference to a certain standard or method. For example, you can be accurate with your answer but you can be precise with the method of calculation.

Accuracy may also refer to the truthfulness of data and records. For example, you can have accurate demographic data of the people in a city. But, in this case precise would refer more to the inferences you have drawn from the accurate date in your possession about the demography of the city in question.

Both accuracy and precision can also refer to results obtained from mechanical objects like a compass and watch. For example, if you have tuned or set your watch and compass accurately, it will be able to give you the current time and direction at any given moment with precision.

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

i think the answer is a, hope this is right, that would be my best guess.
