Electric vehicle 72V battery 3000W controller 2500W motor theory can run fast? 2000W motor? How far can run in theory?

Electric vehicle 72V battery 3000W controller 2500W motor theory can run fast? 2000W motor? How far can run in theory?

Do you mean Hussars? Now Hussars are all equipped with this configuration. There is no difference between 2000W and 2500W. If a group of batteries can run about 40km, it will be useless. Now Hussars are double 72V, with 12 batteries in total. Theoretically, they can run 80km and speed about 70km / h

5 * 999 + 5 + 99 * 7 + 7 + 3 * 9 + 3 + 9 help how to calculate easily. Thank you

Original formula = 5x (999 + 1) + 7x (99 + 1) + 3x (9 + 1) + 9 = 5000 + 700 + 30 + 9 = 5739
I believe that the landlord is smart, I slowly understand the problem-solving ideas, find some similar problems to do, draw inferences from one instance will soon be able to master ~ I wish you good luck!

What is the volume in letters

V is volume. M ^ 3 is the first letter of volume

50 × 38.2 × 0

50×38.2×0.2
＝（50×0.2）×38.2
＝10×38.2
＝382

In a circuit, there is a light bulb, through which the current intensity is 0.4 a, and then a 10 ohm resistor is connected in series, the current intensity is reduced to 0.3 a
If the power supply voltage remains unchanged, the original electric power of the bulb is_______ tile

This problem can be solved first bulb resistance R
According to Ohm's law, 0.4A * r = 0.3A * (R + 10)
The solution is r = 30 Ω, so the supply voltage U = 30 Ω * 0.4A = 12V
So the original power of the bulb is p = UI = 12V * 0.4A = 4.8w

Please, it's urgent. 50 is OK

Life is so beautiful

Life is a field wind in spring, fresh and pleasant, with a light ray of comfort, giving people infinite reverie. Starting from life, I appeal to the specific image, and come from afar. I like to walk on the path in the field, enjoy the gloomy trees, smell the smell of wheat, It can always make people relaxed and happy. On this road, I have seen the smiles of countless passers-by, and I have seen many strange flowers and plants
