The basic provisions for setting up road parking lots are as follows: limit the permitted parking range and the specified parking time. Road sections that can only be set during off-peak hours and do not affect the smooth traffic must be adjusted with the changes of municipal engineering construction and dynamic traffic.
The Significance of P in Physics
In physics, P is a physical term, and the work done by current per unit time is called electric power.
The physical quantity used to express the speed of electric energy consumption is expressed by P, the unit is Watt, and the symbol is W. In geography, P is a geological symbol.
Lamps and appliances are marked with rated voltage (U0) and power (P0). The current of normal light emission, I is equal to P0 divided by U0. I=P0/U0。
