Explanation:
In order to determine the work done, we will first calculate the internal energy as follows.
=
= 0.171 kJ
Now, we know that relation between internal energy and pressure according to the first law of thermodynamics is as follows.
= q + w
Since, in the given situation heat energy (q) is equal to 0. Therefore,
= w
= 0.171 kJ
Thus, we can conclude that minimum work that must be supplied to accomplish this compression process is 0.171 kJ.

Answer:
The magnitude of the resultant force is
The direction of the resultant force is from the horizontal plane
Explanation:
Generally when resolving force, if the force (F )is moving toward the angle then the resolve force will be while if the force is moving away from the angle then the resolved force is
Now from the diagram let resolve the forces to their horizontal component
So
Now resolving these force into their vertical component can be mathematically evaluated as
Now the resultant force is mathematically evaluated as
substituting values
The direction of the resultant force is evaluated as
substituting values
from the horizontal plane
