According to the Second Law of Thermodynamics, processes tend to develop in a way in which the Entropy of the system tends to increase, resulting in energetic disorganization and energy dissipation. Is it possible to reverse the process?a.
'No, as changes can be easily reversed.'
b.
'Yes, provided there is a reduction in entropy.'
c.
'Yes, provided there is external energy transfer to the system.'
d.
No, as processes cannot be reversed.
e.
'Yes, provided there is an increase in entropy.'

Beverages can be chilled more quickly using styrofoam boxes containing ice and a little commercial coarse salt. In this process, the ice melts with consequent formation of liquid and cooling of the beverages. An erroneous interpretation, based on common sense, relates this effect to the great ability of coarse salt to remove heat from the ice. From a scientific point of view, rapid cooling occurs due to more efficient heat transfer between the ice, salt, and beverages.

A technician from an electronics company is working on a circuit involving three capacitors in series. The capacitors have capacitances of 6μF, 8μF, and 12μF, respectively. Assuming the potential difference applied to the capacitors is 60V, determine the charge stored in each capacitor and the equivalent capacitance of the series configuration.

A person with height $$\boldsymbol{h}$$ stands in front of a pinhole camera in order to produce an image on the opposite side of the camera that corresponds to three quarters $$(3 / 4)$$ of their height. Knowing that the pinhole camera has a depth $$\boldsymbol{d}$$, what will be the distance between the person and their image?

The prefix table is used to represent physical quantities more accurately. For example, we can use the prefix 'deci' to represent 0.1 times the unit. If we have 1 decimeter, that means 0.1 meters. Which of the prefixes below means 0.000001 times the unit?
