Start with:2 log8 x = log8 16 Bring the "2" into the log:log8 x2 = log8 16 Remove the logs (they are same base): x2 = 16 Solve:x = −4 or +4 But ... but ... but ... we can't have a log of a negative number! So the −4 case is not defined. Answer: 4...

electric charges that build up on the surface of materials or substances. These charges remain static until they are grounded, or discharged. This type of electricity is formed due to fiction. Basically, the phenomenon ofstatic electricityarises when the positive and negative charges are separated...
hexafluoride gas attracts free electrons. as the circuit contacts are opened, the gas flows through the chamber striking the arc. the free electrons are then absorbed by the sf6 resulting in immobile negative ions. for the arc to extinguish completely, the insulating strength of the medium should...
The figure below shows three capacitors connected in parallel, with all the respective positive and negative terminals connected together (assuming the caps are polarized). The total capacitance of this arrangement is simply the sum of all the capacitances of all the capacitors in the circuit. This...

Time is often an issue and sure enough you have: "float t1=micros(); float td=micros()-t1;" So, here, td can be either zero or negative (on some platforms, maybe not yours). So any division by td is now suspect (NAN!). ...
Tabulations such as Abramowitz and Stegun [1] should be consulted for details.ConventionsThe mathematics and applications of complex numbers have an inherent ambiguity associated with the positive and negative signs of the square root of (-1). In relativistic quantum electrodynamics, the two signs ...
The anode has a negative potential with respect to the solution while the cathode has a positive potential with respect to the solution. Thus, a potential difference develops between two electrodes of the galvanic cell. This potential difference is known as cell potential. ...
when the diode is forward biased, it acts as a closed switch. but, during the negative half cycle of the ac source voltage, the equivalent circuit becomes as shown in the figure below when a diode is reverse biased, it acts as an open switch. since no current can flow to the load, ...
