Why are theoretical and experimental values different?
Why are theoretical and experimental values different? Why is there a difference in theoretical and experimental probability? The relationship between the two is that you’ll find if you do the experiment enough times, the experimental probability will get closer and closer to the theoretical probability’s answer. What is the accepted value in percent error? accepted […]
What happens if a switch is closed in a circuit?
Can you work on live electrical equipment?
Can you work on live electrical equipment? (Live parts that operate at less than 50 volts to ground need not be de-energized if there will be no increased exposure to electrical burns or to explosion due to electric arcs.) The message is clear: never work on live circuits unless it is absolutely necessary. What is […]
What is the working principle of a motor?
What is the working principle of a motor? The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force. What is an electric motor state its principle? Electric motor: An […]
How do you do a dry park test of a steering system?
How do you do a dry park test of a steering system? The ‘Dry-Park’ Performance Test After starting the engine, check for a “bump” or movement in the steering wheel as the engine starts. Stand outside the vehicle and rock the steering wheel. If there’s excess play or if you hear knocking noises, the power […]
What is the de Broglie wavelength of an electron accelerated from rest through a potential difference of V volts?
What is the de Broglie wavelength of an electron accelerated from rest through a potential difference of V volts? 227nm. What is the de Broglie wavelength of an electron accelerated from rest by a potential difference of 54 V? Example 2: Calculate the de Broglie wavelength for an electron that is accelerated inside a potential […]
Why is carbon monoxide dangerous?
Why is carbon monoxide dangerous? Carbon monoxide is harmful when breathed because it displaces oxygen in the blood and deprives the heart, brain and other vital organs of oxygen. Large amounts of CO can overcome you in minutes without warning — causing you to lose consciousness and suffocate. Also, CO poisoning poses a special risk […]
What is centrifugal force explain?
What is centrifugal force explain? Centrifugal force, a fictitious force, peculiar to a particle moving on a circular path, that has the same magnitude and dimensions as the force that keeps the particle on its circular path (the centripetal force) but points in the opposite direction. Centrifugal force. Quick Facts. Centrifuge. Inertial force. What is […]
How does a wind power station work?
How does a wind power station work? Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. How much do you get paid to have […]
