Because of a difference in temperature.
To solve this problem it is necessary to consider two concepts. The first of these is the flow rate that can be defined as the volumetric quantity that a channel travels in a given time. The flow rate can also be calculated from the Area and speed, that is,
Q = V*A
Where,
A= Cross-sectional Area
V = Velocity
The second concept related to the calculation of this problem is continuity, which is defined as the proportion that exists between the input channel and the output channel. It is understood as well as the geometric section of entry and exit, defined as,
Our values are given as,
Re-arrange the equation to find the first ratio of rates we have:
The second ratio of rates is
The work done by the two forces in moving the chandelier to the given distance is 5,091.2 J.
<h3>
Work done by a single force on the chandelier</h3>
The work done by a single force on the chandelier is determined by taking the net horizontal force applied on the chandelier over the given distance.
where;
is frictional force = 0 (smooth surface).
<h3>Work done by the two forces</h3>
When the two forces combine to pull the chandelier, the total work done will be shared by the two forces.
Thus, the work done by the two forces in moving the chandelier to the given distance is 5,091.2 J.

Answer:
C. magnetic force
Explanation:
A magnetic field is responsible for the magnetic forces acting on a moving charge, so we can say that the direction of the magnetic field is determined by the magnetic forces. In the case of a conductor traversed by electric current and subjected to the presence of a magnetic field, we will also have the action of a magnetic force, since the current represents an orderly movement of electric charges.
An example of the application of magnetic force occurs in the TV tube, where a set of coils (artificial magnets), with their magnetic fields, enables the action of magnetic forces that deflect electron beams, causing them to traverse the entire screen. These electron beams sweep the phosphor-coated screen, line by line, from left to right and top to bottom, allowing the image to emerge.
