Only watts (power) can produce work (energy) because of the phase relationship of the voltage and current in an alternating current, electric power system. With watts, the portion of the current and voltage that are in-phase with each other can do work. Vars, on the other hand are volt-amps reactive, which are out-of-phase with each other. Since Vars cannot do work, their existence in the electric power system is parasitic. The reactive current which flows in a power line, for instance uses a portion of line capacity, and also causes heating (I^2 * R power loss) due to the inherent resistance of the conductors.
So, in the construction of a simple electromechanical meter, measuring Watt-hours or Var-hours, the respective current and voltage coils used to drive the rotating disk are situated to produce torque. For a Var Hr meter, the coils are rotated 90 degrees relative to each other to counter the lagging or leading phase shift and thus produce torque.
The connection time is the scheduled departure time of your connecting flight. The layover time is the amount of time between the arrival of your first flight and your connection time.
high latency means you have a good connection, low latency means you have a baad connection
A: impressed voltage is a mechanical connection involved induced has no mechanical connection except for proximity
A tap is the connection for the water main and a faucet comes after the TAP

The difference between a dial up connect and a direct connection is that a dial up requires a connection from a phone line to a PC and the data capacity is smaller. A direct connection can transmit large amounts of data at higher speeds.

Ren and Li are two key principles in Confucian philosophy. Ren refers to the concept of benevolence, kindness, and humanity towards others, while Li encompasses rituals, propriety, and etiquette that govern social interactions. Together, Ren and Li form the foundation for maintaining harmony and order in society according to Confucian values.

Bullying involves repeated aggressive behavior intended to intimidate or harm another person emotionally, socially, or physically. Violence typically refers to actions or behaviors that cause physical harm or injury to another person. While bullying can be a form of violence, not all violence involves the repeated and intentional targeting of an individual as seen in bullying.
