What is the working principle of inductor? An inductor is a passive electronic component which is capable of storing electrical energy in the form of magnetic energy. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will generate a […]

Acid rain is caused largely by sulphur dioxide and oxides of nitrogen emitted by industrial activities such as […]
What happens if mass and velocity are doubled?
What happens if mass and velocity are doubled? Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum. What happens to the kinetic energy when the mass and velocity is […]
Why does the queen hold her wrist?
Why does the queen hold her wrist? You may have noticed that the Queen often clasps her hands together at events but it’s not to avoid awkward handshakes. Instead, the pose is intended to show that she is not threatening. “The Queen’s signature pose is the handclasp. This is a demure defence posture and it […]
Does it mean if data are reproducible but not accurate?
What are two requirements for current flow?
What are two requirements for current flow? To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper […]
Is friction necessary for a body to roll?
Is friction necessary for a body to roll? Yes friction is necessary to the body to roll. The minimum friction is that when the body moves easily by using 1 Newton of force. How is the draft calculated in rolling? Explanation: During rolling process, the workpiece gets squeezed, causing the thickness of the workpiece to […]
What happens to electrons when they reach a light bulb?
What happens to electrons when they reach a light bulb? 2 Answers. Electrons are accelerated by the field inside the incandescent filament (the voltage drop over the light bulb is large, the field is relatively strong). The electron then interacts with the lattice, losing its energy to thermal vibrations. Then gets accelerated again, etc. Is […]
Is it safe to live by a nuclear power plant?
Is there anything more powerful than gamma rays?
Is there anything more powerful than gamma rays? The measurement is exceedingly difficult since cosmic rays can outnumber gamma-rays at these energies by a factor of 10,000 to 1 or more! As the gamma-ray is making its way to our telescopes, it has to traverse through space, where there are photons and particles all around […]
