On what principle is an AC generator based? AC generators work on the principle of Faraday’s law of electromagnetic induction which states that electromotive force -EMF or voltage – is generated in a current-carrying conductor that cuts a uniform magnetic field. What is generator working principle? Electric generators work on the principle of electromagnetic induction. […]
Do birds feel earthquake while flying?
Do birds feel earthquake while flying? Birds and animals “feel” things in more dimensions than humans do. Birds for example are very sensitive to magnetic fields. Earthquakes being tectonic activity, I can’t see how it won’t have small impact on the earth’s magnetic field in the region. This could in turn be felt by the […]
How the mind and body are connected?
How the mind and body are connected? The brain and body are connected through neural pathways made up of neurotransmitters, hormones and chemicals. These pathways transmit signals between the body and the brain to control our everyday functions, from breathing, digestion and pain sensations to movement, thinking and feeling. What three levels did Plato say […]
What are the negative effects of gamma rays?
What are the negative effects of gamma rays? The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer. How can we reduce exposure to gamma rays? […]
What are the similarities between an element and a compound?
What are the similarities between an element and a compound? On first glance, elements and compounds might appear different, yet they share many similarities, like being made up of atoms and having bonds linking their atoms together. Elements and compounds also share the qualities of being both pure and homogeneous substances. What do elements and […]
Do speed radar guns take pictures?
Do speed radar guns take pictures? Speed guns do not capture any images, unlike the Truvelo and ‘Long Ranger’ cameras, that can capture a driver’s face. What happens if you get caught with a radar detector? If you’re caught using radar jammers, you’ll likely end up with an expensive fine and also confiscation of the […]
Which surface has the most amount of friction?
Which surface has the most amount of friction? Rougher surfaces have more friction between them than smoother surfaces. That’s why we put sand on icy sidewalks and roads. You can’t slide as far across ice with shoes as you can on the blades of skates (see Figure below). The rougher surface of the soles of […]
How do you tell if rotors need replacing?
How do you tell if rotors need replacing? Additionally, brake rotors may also need replacement when any of the following signs appear: After pressing the brake pedal, the driver feels a vibration in the steering wheel and/or the brake pedal. Cause: Pad Deposits. The brakes produce very loud noises when braking. The brake rotor has […]
Why magnetic field is created around a current carrying conductor?
Why magnetic field is created around a current carrying conductor? Current is generally defined as the rate of flow of charge. The same principle can be applied here, moving charges produce magnetic fields which are proportional to the current and hence a current carrying conductor produces magnetic effect around it. … Does a current carrying […]
What is meant by inertia?
What is meant by inertia? Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object’s speed, or direction of motion. Inertia comes from the Latin word, iners, meaning idle, sluggish. What are three types of inertia? Types of Inertia Inertia of rest – An object […]
