According to Hooke's law, a 30-N force stretches a spring by 0.73 m if the spring constant k is such that

30 N = k (0.73 m)

k = (30 N) / (0.73 m)

k ≈ 4.1 N/m

alexgriva [62]

The persuasive techniques that were used in the given poster are; Option A; glittering generalities about the viewer. and Option C; fear over a possible outcome

The poster is missing and so i have attached it.

The painting in the attached image was one created by Norman Rockwell released by the United Kingdom's Royal Navy during World War II.

The intentions and message the poster is trying to communicate is very direct because it tells us that  if the workers waste time, the production rate of ships and destroyers will definitely decrease and as such the war will continue and it will take a far longer time to win the war.

The persuasive technique used in this poster is that it shows the glittering generalities about the viewer and from the images fear over a possible outcome.
