(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.

Explanation:
Given
Required
The component of the force in F direction
To do this, we simply calculate the force in the vertical and horizontal direction.
This is calculated as:
--- Horizontal
---- Vertical
So, we have:
--- Horizontal
---- Vertical

Answer:
Diffusion
Explanation:
Diffusion is the tendency of molecules to rise from region of higher concentration to region lower concentration until they are even distributed. The tendency of molecules to move toward areas of lower concentration is called diffusion. Diffusion occurs base on diffusion gradient which is change in quantity of the the molecule with respect to change in variables of the medium. The rate of diffusion varies for different substances and mediums.
