The characteristic of science that is best exemplified by the paragraph presented is "It is falsifiable and reproducible."

<h3>What is science?</h3>

Science can be mostly defined as a set of methods and principles that aim at objectively understanding and explaining the phenomena that occurs in the world.

These set of methods and principle lead to theories and laws that describe how a specific phenomenon occurs.

<h3>What does "It is falsifiable and reproducible"?</h3>

This is a basic principle that implies hypotheses about a specific phenomenon can be tested using experiments and this can lead to either the confirmation of the hypothesis or dispproved. Moreover, same experiments can be used and these will have similar results.

This principle matches the paragraph because the same experiment leads to same results. Moreover, previous ideas about a phenomenon were disproved.

A block of mass
Gennadij [26K]

(a) The work done by the applied force is 26.65 J.

(b) The work done by the normal force exerted by the table is 0.

(c) The work done by the force of gravity is 0.

(d) The work done by the net force on the block is 26.65 J.

<h3>Work done by the applied force</h3>

W = Fdcosθ

W = 14 x 2.1 x cos25

W = 26.65 J

<h3>Work done by the normal force</h3>

W = Fₙd

W = mg cosθ x d

W = (2.5 x 9.8) x cos(90) x 2.1

W = 0 J

<h3>Work done force of gravity</h3>

The work done by force of gravity is also zero, since the weight is at 90⁰ to the displacement.

<h3> Work done by the net force on the block</h3>

∑W = 0 + 26.65 J = 26.65 J

Thus, the work done by the applied force is 26.65 J.

The work done by the normal force exerted by the table is 0.

The work done by the force of gravity is 0.

The work done by the net force on the block is 26.65 J.
