The Heisenberg Uncertainty Principle states that it is impossible to simultaneously know the exact position and momentum of a particle.

The mass defect is the difference between the mass of the nucleus and the sum of the masses of its individual nucleons, indicating the stability and binding energy of the nucleus.

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of quantum numbers.

The specific heat capacity of air at constant pressure is approximately 1.005 J/kg·K.

The specific heat capacity of air is approximately 1.005 J/kg·K.

The specific heat capacity of iron is approximately 0.45 J/g·K.

The standard unit of time in the SI system is the second (s).

The energy required to change a substance from liquid to gas is called the latent heat of vaporization.

The heat required to change a substance from solid to liquid at its melting point is called the latent heat of fusion.

The heat required to change a substance from solid to liquid at constant temperature is called the latent heat of fusion.

The phenomenon where a liquid rises in a narrow tube against gravity is called capillarity.

Surface tension is the phenomenon where a liquid's surface behaves like a stretched elastic membrane due to cohesive forces.

Specific gravity is the ratio of the density of a substance to the density of a reference substance, typically water.

The temperature at which a substance changes from liquid to gas is called the boiling point.

Using Ohm's law, I = V/R = 9V / 3Ω = 3 A.

In parallel, the total current is the sum of the currents: 2 A + 2 A + 2 A = 6 A.

In a parallel circuit, the total current is the sum of the currents in each branch: 2 A + 3 A = 5 A.

Total resistance R = 10Ω + 5Ω = 15Ω. Current I = V/R = 30V/15Ω = 2A.

Total resistance R = 6 + 6 = 12Ω. Current I = V/R = 12V/12Ω = 1A.

Total resistance R = 3Ω + 3Ω = 6Ω. Current I = V/R = 9V/6Ω = 1.5A.

In parallel circuits, the total current is the sum of the currents in each branch: 2A + 3A = 5A.

In parallel circuits, the total current is the sum of the currents in each branch: 3A + 5A = 8A.

In a parallel circuit, the total current is the sum of the currents in the branches: 2 A + 3 A = 5 A.

The total mechanical energy of an object in free fall is conserved, meaning it remains constant as potential energy converts to kinetic energy.

The real power (P) can be calculated using P = Power Factor × Apparent Power. Therefore, P = 0.6 × 100 VA = 60 W.

In series, total resistance R = R1 + R2 = 4 Ω + 6 Ω = 10 Ω.

In reverse bias, a diode exhibits a very small reverse saturation current until breakdown occurs.

The typical forward voltage drop across a silicon diode is approximately 0.7 V.
