1. A serial data line or bus is used for which of the following purposes? C. Transmit pulses from the ignition primary coil to the tachometer12. GM Class 2 communication toggles between B. 0 and 12 V.3. Technician A says that module communications networks are used to reduce the number of wires in a vehicle. Technician B says that a communications network is used to share data from sensors, which can be used by many different modules. Which technician is correct? A. Technician B only4. A magnetic field is created around a wire when A. the wire is connected between two grounds. 5. In most automotive electrical circuits, a relay is used in which of the following situations? C. A lower-voltage circuit controls a higher-voltage circuit.6. A diagnostic scan tool connects to the vehicle using the C. data link connector.7. A diode with high resistance or an infinite reading in both directions is C. reverse biased.8. Two technicians are discussing how capacitors work. Technician A says that, in an open circuit, a capacitor will hold its charge until it’s connected to an external circuit. Technician B says that theoretically a capacitor will hold its charge indefinitely. Who is correct? A. Technician A 9. All of the following can be added to a circuit to reduce electromagnetic interference, except C, a diode.10. Technician A says when you push the horn button, electromagnetism moves an iron bar inside the horn, which opens and closes contacts in the horn circuit. Technician B says most vehicle horn circuits use a relay. Which technician is correct? B. Both Technician A and Technician B11. A/an is a material with four electrons in the valence ring. D. conductor1. Technician A says that dynamic voltage is the voltage (usually of a battery) that exists without a load being applied. Technician B says that open circuit voltage (OCV) is the voltage of the power source (battery) with the circuit in operation. Who is correct? A. Both Technicians A and B2. A technician connects one lead of a digital voltmeter to the positive (+) terminal of the battery and the other meter lead to the battery terminal (B) of the starter solenoid and then cranks the engine. During cranking, the voltmeter displays a reading of 878 mV. Technician A says that this reading indicates that the resistance of positive battery cable is too high. Technician B says that this reading indicates that the starter is defective. Which technician is correct? B. Technician A only... Show More

Option A:The neutral wire and the ground wire.Explanation:Since live wire carries about 220-240 V of AC.The second wire is neutral wire and it carries 0 Voltage.While,the earth wire is grounded and it has no voltage and current.So,there is no potential difference between neutral and ground wire....

Technician BExplanation: It is a known fact that the Throttle Position (TP) sensor, is used by the PCM to determine torque converter engagement and transmission shift points. The TP is a 3 wire potentiometer, often used for vehicle fuel-management systems which includes a voltage of +5V applied to the PCM, not the resistive layer.... Show More

The neutral wire and the ground wire.Explanation:The hot wire provides the current source. The neutral wire is connected to complete the circuit and provides return path to the current. It is connected to ground Earth. The ground wire is connected to the ground as well but it connects to the metal parts of the appliance and is present to prevent from any shock hazard due to a short circuit. Thus, there would be no potential difference between the neutral and the ground wire.... Show More

The student’s vertical speed when he was thrown out = 14.14 m/sSpeed of the student if he hit the ground = 14.14 m/sExplanation:Step 1:It is given that the student reached a maximum height of 10 meters when he was thrown out. The initial speed with which he was throw is to be estimated. Step 2: The equation of motion connecting initial velocity, final velocity and distance is where v is the final velocity, u is the  velocity with which he was thrown, a is acceleration due to gravity and s is the height.The final velocity at the highest point 10 meters will be 0s = 10 ma = -10 m/0 = + 2*(-10)*10u = = 14.14 m/sStep 3:The final speed when the student hits the ground will be the same as initial speed of the student when he was thrown out.So the final speed of the student if he hit the ground would be 14.14 m/sStep 4:The student’s vertical speed when he was thrown out = 14.14 m/sSpeed of the student if he hit the ground = 14.14 m/s...
