Answer:
The answer is the third option, the minimum force required to overcome static friction and move an object.
Explanation:
The first choice is talking about an object moving, and anything moving relates to <em>kinetic </em>friction, not static friction. I don't think it's the fourth option because, even with the net force being 0, the object could still be moving (again relating to kinetic friction).

D.
Thermodynamics is the study of how different types of energy is transferred through the chemical systems
Answer:
Explanation:
Since the fly accumulated a positive charge of +73pC, it must have lost an equal number of negative charge of -73pC to the surface (because the housefly was neutral to begin with).
Therefore, to answer our question we have to ask ourselves <em>how many electrons combine to make -73pC of charge? </em>
The answer is since one electron carries a charge of 
, the number 
of electrons that make up -73pC 
are
Thus, the housefly lost about 456 million electrons to the surface!
Answer:
Explanation:
Kinetic energy is given by the following equation:
, where 
is mass in 
and 
is velocity in 
.
Since the cell phone's mass is given in grams, we need to convert this into kilograms:
.
Therefore, the kinetic energy of the cell phone is:
.
