Does the following argument appeal to the Method of Agreement, the Method of Difference, the Joint Method of Agreement and Difference, or Correlation? "45 patients were admited to Mercy Hospital for pneumonia in December. They were all given standard treatment for pneumonia. After 5 days, 30 of them were well enough to go home. The other 15, however, somehow acquired other infections and were nto well enough to be released for 14 days. The only relevant favor common to these 15 is this: THhey all stayed in the same ward (different from the ward that the other group stayed in). Something about staying in that ward is the cause of the prolonged illness."

a.
Joint Method of Agreement and DIfference

b.
Correlation

c.
Method of Agreement

d.
Method of Difference

Explanation:

If the arrow points to the right, then the force is positive.

If the arrow points to the left, then the force is negative.

Also, remember that the force does not relate (necessarily) to the mass, so the different blocks having different masses is not an important factor in this problem.

Let's find the force in each block.

A)

Here we have a positive force of 3N and a negative force of 1N

Then the net force (the sum of all the forces) is:

F = 3N  - 1N = 2N

B)

Here we have two positive forces, one of 1N and other that I cant see, I guess that it is 3N

Then the net force is:

F = 1N + 3N = 4N

C)

Here we have two negative forces of 2N

Then the net force is:

F = - 2N + ( - 2N) = -4N

D)

Here we have a single force of 2N that is negative, then the net force is:

F = -2N

E)

Here we have a negative force of 3N and a positive force of 2N

then the net force is:

F = -3N + 2N = -1N

Then, the order of greatest to least (from positive to negative) is:

B, A, E, D, C
