Answer:
<h2>True Most Especially in the field of Automotive Engineering</h2>
Explanation:
Normally, before the introduction of vehicle diagnostics when a vehicle, mostly automobile/car break down, one could be the vehicle mechanic would only suspect one or two related faults based on the present working condition of the car, the mechanic would perform some trial and error before he could fix the car.
But in recent times, the introduction of vehicle diagnostics devices and software has changed the order as vehicles can be connected to a computer that will scan and tell what the problem is before a possible fix.

<em>T = 25.41 Nm</em>
Explanation:
Calculating Nsync (Synchronous Speed):
![Nsync = 120f/P](https://tex.z-dn.net/?f=Nsync%20%3D%20120f%2FP)
![Nsync = 120 x 120 / 4\\Nsync = 3600 rpm](https://tex.z-dn.net/?f=Nsync%20%3D%20120%20x%20120%20%2F%204%5C%5CNsync%20%3D%203600%20rpm)
![Wsync = 3600 * 2\pi /180\\Wsync = 377 rad/s](https://tex.z-dn.net/?f=Wsync%20%3D%203600%20%2A%202%5Cpi%20%2F180%5C%5CWsync%20%3D%20377%20rad%2Fs)
Calculating s (Slip):
![s = (Nsync - Nm) / Nsync \\[tex]s = (3600-2464)/3600\\s = 0.3156](https://tex.z-dn.net/?f=s%20%3D%20%28Nsync%20-%20Nm%29%20%2F%20Nsync%20%5C%5C%3C%2Fp%3E%3Cp%3E%5Btex%5Ds%20%3D%20%283600-2464%29%2F3600%5C%5Cs%20%3D%200.3156)
Calculating Vth (Thevenin Voltage):
![Vth = Vph (Xm / \sqrt{Rs^{2} + (Xs+Xm)^{2} })\\Vth = 209 (76 / \sqrt{(2.3)^{2} + (1.3 + 76)^{2} }\\Vth = 205.39 V](https://tex.z-dn.net/?f=Vth%20%3D%20Vph%20%28Xm%20%2F%20%5Csqrt%7BRs%5E%7B2%7D%20%2B%20%28Xs%2BXm%29%5E%7B2%7D%20%20%7D%29%5C%5CVth%20%3D%20209%20%2876%20%2F%20%5Csqrt%7B%282.3%29%5E%7B2%7D%20%2B%20%281.3%20%2B%2076%29%5E%7B2%7D%20%20%7D%5C%5CVth%20%3D%20205.39%20V)
Calculating Rth (Thevenin Resistance):
Calculating Xth (Thevenin Reactance):
Xth = Xs = 1.3 ohm
Calculating Torque:
![T = (3Vth^{2}Rr/s) / (Wsync[(Rth+Rr/s)^{2} + (Xth + Xr)^{2}])\\T = (3*205.39*0.7/0.3156) / 377[(2.22+0.7/0.315)^{2} + (1.3+1.8)^{2}]](https://tex.z-dn.net/?f=T%20%3D%20%283Vth%5E%7B2%7DRr%2Fs%29%20%2F%20%28Wsync%5B%28Rth%2BRr%2Fs%29%5E%7B2%7D%20%2B%20%28Xth%20%2B%20Xr%29%5E%7B2%7D%5D%29%5C%5CT%20%3D%20%283%2A205.39%2A0.7%2F0.3156%29%20%2F%20377%5B%282.22%2B0.7%2F0.315%29%5E%7B2%7D%20%2B%20%281.3%2B1.8%29%5E%7B2%7D%5D)

Answer:
The total energy of the motor of the electric vehicle is 1.902 × 10⁸ joules.
Explanation:
Power is the rate of change of work in time, since given input is average power, the total energy (
) of the motor of the electric vehicle, measured in joules, is determined by this formula:
![\Delta E = \dot W \cdot \Delta t](https://tex.z-dn.net/?f=%5CDelta%20E%20%3D%20%5Cdot%20W%20%5Ccdot%20%5CDelta%20t)
Where:
- Average power, measured in watts.
- Time, measured in seconds.
Now, let convert average power and time into watts and seconds, respectively:
Average Power
![\dot W = (50\,hp)\times \frac{746\,W}{1\,hp}](https://tex.z-dn.net/?f=%5Cdot%20W%20%3D%20%2850%5C%2Chp%29%5Ctimes%20%5Cfrac%7B746%5C%2CW%7D%7B1%5C%2Chp%7D)
![\dot W = 3.730\times 10^{4}\,W](https://tex.z-dn.net/?f=%5Cdot%20W%20%3D%203.730%5Ctimes%2010%5E%7B4%7D%5C%2CW)
Time
![\Delta t = (1\,h)\times \frac{3600\,s}{1\,h} + (25\,min)\times \frac{60\,s}{1\,min}](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%20%281%5C%2Ch%29%5Ctimes%20%5Cfrac%7B3600%5C%2Cs%7D%7B1%5C%2Ch%7D%20%2B%20%2825%5C%2Cmin%29%5Ctimes%20%5Cfrac%7B60%5C%2Cs%7D%7B1%5C%2Cmin%7D)
![\Delta t = 5.100\times 10^{3}\,s](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%205.100%5Ctimes%2010%5E%7B3%7D%5C%2Cs)
Then, the total energy is:
![\Delta E = (3.730\times 10^{4}\,W)\cdot (5.100\times 10^{3}\,s)](https://tex.z-dn.net/?f=%5CDelta%20E%20%3D%20%283.730%5Ctimes%2010%5E%7B4%7D%5C%2CW%29%5Ccdot%20%285.100%5Ctimes%2010%5E%7B3%7D%5C%2Cs%29)
![\Delta E = 1.902\times 10^{8}\,J](https://tex.z-dn.net/?f=%5CDelta%20E%20%3D%201.902%5Ctimes%2010%5E%7B8%7D%5C%2CJ)
The total energy of the motor of the electric vehicle is 1.902 × 10⁸ joules.
Answer:
Following are the response to the given question:
Explanation:
In the given question, A curve one would be to "reject" them. Within this way, people are directly non-confrontationally off from their amorous interests or advances. The curve looks much like a current through the unidirectional load, and it has only a good maximum value. It seems like the total rating of the complete wave rectifier that is illustrated below, the present vas temporal curve please find it.
