Perceiving machines" are used by the U. S. Postal service to "read" the addresses on letters and sort them quickly to their correct destinations. Sometimes, these machines cannot read an address, because the writing on the envelope is not sufficiently clear for the machine to match the writing to an example it has stored in memory. Human postal workers are much more successful at reading unclear addresses, most likely because of:.A. Bottom-up processing.
B. Top-down processing.
C. Their in-depth understanding of principles of perception.
D. Repeated practice at the task.

B. Top-down processing.

Explanation:

In psychology, "sensation and perception" generally involves two different processes including top-down processing and bottom-up processing.

Top-down processing: The term "top-down processing" is described as the phenomenon that involves different perception which is being driven by cognitive processes. In top-down processing, an individual's brain utilizes specific information that has previously been brought up into his or her brain to the sensory system of the person.

In the question above, the given statement signifies the "top-down processing".

a. formula: f=ma or f/m=a

10,000n/1,267kg≈7.9m/

b. formula: a= and s=d/t

speed= 394.6/15

s=26.3m/s

a=

a=1.75m/

c. 7.9-1.75=difference of 6.15m/

d. the force that most likely caused this difference is friction forces
