solved assignment problems mathematical induction

Betty completed solving 14 problems in her math assignment. How many problems were in her assignment, if she had to solve 18 more problems to complete the assignment? => 40 or 44 or 37 or 32..

Introduction - The word 'Induction' means method of reasoning from individual cases to general ones or from observed instances to unobserved ones. Many important mathematical formulae are such that a result is formed by some means which does not provide for a direct proof. ..

Magnetic Induction - If you hold a bar magnet near or in contact with a soft iron nail as shown in figure, the nail becomes a magnet by induction. The nail retains its magnetism only as long as the magnet is held near it or in contact with it. It will even pick up several other ..

Induction furnace separates certain metals from their ores. It is done by heating the metal. The type of heating done is called induction heating. This heating can be done using eddy currents. The metal to be heated is placed in a high frequency changing magnetic field. Strong ..

If you hold a bar magnet near or in contact with a soft iron nail as shown in figure, the nail becomes a magnet by induction. The nail retains its magnetism only as long as the magnet is held near it or in contact with it. It will even pick up several other nails. But is loses its magneti..

Mutual Inductance - We know that if a current builds up or varies in a coil, the flux change leads to induced e.m.f in the same coil. This can happen event mutually between two interacting coils are close together, and if current is passed in one of them, it sets up a magnetic flux surrou..

We know that if a current builds up or varies in a coil, the flux change leads to induced e.m.f in the same coil. This can happen event mutually between two interacting coils are close together, and if current is passed in one of them, it sets up a magnetic flux surrounding itself. When the second ..

Michael Faraday the English scientist was the first person to prove that a magnet can create a current To test this he moved a magnet towards and away from the coil of wire connected to a galvanometer He observed that there was a deflection in the galvanometer indicating that a current is i..
