Transformers work on the principle of electromagnetic induction, where a changing magnetic field induces an electromotive force (EMF) in a coil.

An electric generator works on the principle of electromagnetic induction, where mechanical energy is converted into electrical energy by moving a conductor through a magnetic field.

An electric motor operates on the principle of the Lorentz force, which states that a current-carrying conductor in a magnetic field experiences a force.

A potentiometer measures voltage by balancing it against a known voltage, allowing for accurate voltage measurements.

The principle of conservation of momentum states that the total momentum of a closed system remains constant if no external forces act on it.

The principle of superposition states that when two or more waves overlap, the resultant displacement is the sum of the individual displacements.

The principle of superposition states that when two or more waves overlap, the resultant displacement is the sum of the individual displacements.

The principle of superposition states that when two or more waves overlap, the resultant wave is the sum of the individual waves.

There are 26 red cards in a deck of 52. Probability = 26/52 = 1/2.

There are 4 aces in a deck of 52 cards. Therefore, the probability P(ace) = 4/52 = 1/13.

The possible outcomes for a sum of 7 are (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) which gives us 6 favorable outcomes. Total outcomes when rolling two dice = 6 * 6 = 36. Therefore, P(sum of 7) = 6/36 = 1/6.

Even numbers on a die: 2, 4, 6. Probability = 3/6 = 1/2.

Even numbers on a die = 2, 4, 6. Probability = 3/6 = 1/2.

The even numbers on a die are 2, 4, and 6. There are 3 even numbers out of 6 total numbers, so the probability is 3/6 = 1/2.

There are 5 vowels (A, E, I, O, U) in the English alphabet of 26 letters. Therefore, P(vowel) = 5/26.

Nuclear fission is the process in which a heavy nucleus splits into two lighter nuclei, releasing energy in the process.

Addition polymerization is the process where monomers add together without the loss of small molecules.

Condensation polymerization is the process where a polymer is formed by the elimination of a small molecule.

Sublimation is the process where a solid changes directly into a gas without passing through the liquid state.

The process of creating a polymer from monomers is called polymerization.

The product formed is Fe (iron) when Fe2O3 is reduced by carbon monoxide.

(1 + i)(1 - i) = 1 - i^2 = 1 - (-1) = 2.

In multiplication, the result should have the same number of significant figures as the factor with the least significant figures. 3.00 has 3 significant figures and 2.5 has 2 significant figures, so the result should have 2 significant figures: 7.5.

The complete combustion of an alkane produces carbon dioxide and water.

The complete combustion of an alkyne produces carbon dioxide (CO2) and water (H2O).

The complete combustion of propane produces carbon dioxide (CO2) and water (H2O).

The complete hydrogenation of 2-butyne results in butane.

(1 + i)(1 - i) = 1^2 - i^2 = 1 - (-1) = 2.

z1 * z2 = (1 + i)(1 - i) = 1 - i^2 = 1 + 1 = 2.

Decarboxylation of sodium acetate produces methane.
