4-a.b.c. The image depicts a schematic diagram of a three-phase winding arrangement, commonly used in electrical engineering for motors or generators. The diagram shows a circular assembly with multiple windings distributed in groups around the circumference. These windings represent coils where each phase is connected to a specific group of coils.- **L1, L2, L3:** These labels indicate the three phases of the winding system. Each phase is connected to windings in corresponding segments around the circle. - **Windings:** Illustrated as spiral shapes, these represent coils of wire. The arrangement of these windings is crucial for creating a rotating magnetic field when an electrical current passes through them.- **Segments:** The windings are organized into distinct segments, indicating the structured distribution of coils for phase balancing and optimal electromagnetic performance.Understanding this arrangement is vital for studying the operational principles of three-phase electrical machines. The symmetrically distributed windings ensure balanced phase currents, minimizing vibrations and promoting efficient operation. **Course #1105 Transformers**3. **What must be the speed of a six-pole 25-Hz synchronous generator?** a) 500 rpm b) 900 rpm c) 1200 rpm d) none of the above 4. **A three-phase generator has a load of 100 kW per phase at a power factor of 80 percent, lagging.** A) **What is the three-phase kilowatt load?** a) 30.1 kW b) 300 kW c) 375 kW d) none of the above B) **What is the three-phase kilovoltampere load?** a) 30.1 kVA b) 300 kVA c) 375 kVA d) none of the above C) **What is the line current if the line voltage is 7200 V?** a) 30.1 A b) 300 A c) 375 A d) none of the above 5. **The line voltage of a wye-connected 2400-V 600-kVA unity power factor AC generator is reconnected for delta operation.

I need an expert solution in MATLAB language for the question, and I need the solution to be using MATLAB and in the form of an image. I do not need any notes with the program, just an explanation at the end of the image. By the way, two questions. Q2. Write a MATLAB user-defined function, freefall(), that computes the velocity and the distance of a free fall object. The velocity and the distance of a free fall object can be written as: v = gt y = yo+gt² where yo is the initial position, t is the time travelled and g is the acceleration due to gravity (- 9.81 m/s2). Note that the initial position can only be a scalar value. Q7. Write a user-defined MATLAB Function for the following math function: ((xy-5)² z = if x, y > 0 elsewhere The inputs to the function are x and y, where the output is z.
