Cho sơ đồ lưới như hình bên. Biết điện áp định mức của trạm biến áp là 35/10 kV.
Toàn bộ đường dây của mạng dùng loại dây
AC-95 ( r0 = 0,37 Ω/km; x0 = 0,35 Ω/km),
chiều dài cho trên hình vẽ. Đoạn dây 2-4 có
phụ tải phân bố đều với mật độ 600 kW/km,
cosφ=0,8 (tổn thất công suất trên đường dây
và trong máy biết áp cho phép tính gần đúng
với Uđm ở mọi vị trí của lưới).
Yêu cầu xác định chi tiết:
 Tổng tổn thất công suất trên đường dây lưới 10 kV ?.
 Tổng tổn thất điện năng một năm của trạm?

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.

You are in a car that is traveling along highway 99 at a constant speed of 16 m/s. suddenly you see a truck also traveling at a constant speed (3.0 m/s) that is on a track to cross your lane from an alley on the right and is moving into your lane (which you can’t get out of, because of broader safety concerns like head on traffic in the other lane). your car’s maximum acceleration is 6.0 m/s2 (either way, gettingfaster or slower) and your reaction time of 0.75 s between first seeing the truck and applying the brake or the accelerator. the distance from the side street, where you first notice the truck, to the right edge of your lane is 2.0 m and the lane also has a fixed width of 4.0m, check for yourself that all these numbers are reasonable. you will assume a reasonable size for your car. the truck is 3.0 m wide.a) how long will it take the truck from the moment you notice it, to block enough of your lane so you can’t slip past while also staying in your own lane (in seconds)? b) how far will your car travel (in meters) while your brain is figuring out what to do? c) if you decide that braking is in your best interests how long will it take you to come to a complete stop once you begin the process of braking (in s)? d) what is the minimum distance (in m) you must be from the truck to successfully stop before hitting
