The atomic mass of Sodium (Na) is approximately 22.99 u.

The atomic number of Carbon is 6, which is the number of protons in its nucleus.

The atomic number of Oxygen is 8.

The average duration of a human menstrual cycle is approximately 28 days.

Average power (P) is given by P = V × I × PF. Here, P = 230 V × 5 A × 0.8 = 920 W.

When the power factor is 1, the average power consumed is maximum and is given by P = V_rms × I_rms.

The average volume of blood in an adult human body is approximately 5 to 6 liters.

The base unit of mass in the SI system is the kilogram (kg).

The base unit of temperature in the SI system is Kelvin (K).

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

The cell is the basic structural and functional unit of life, as it is the smallest unit that can carry out all life processes.

The basic unit of classification in biology is the species, which is defined as a group of organisms that can interbreed and produce fertile offspring.

A gene is the basic unit of heredity, responsible for the transmission of traits from parents to offspring.

The cell is the basic unit of life as it is the smallest structural and functional unit of an organism.

Proteins are made up of amino acids, which are their basic building blocks.

The boiling point of water at standard atmospheric pressure is 100°C.

The boiling point of alcohols increases with molecular weight due to stronger hydrogen bonding.

Primary amines have higher boiling points than secondary and tertiary amines due to stronger hydrogen bonding.

Alcohols have higher boiling points than alkanes due to hydrogen bonding.

Amines have higher boiling points than alkanes due to hydrogen bonding.

Carboxylic acids have higher boiling points than alcohols due to stronger hydrogen bonding.

Primary amines have higher boiling points due to stronger hydrogen bonding compared to secondary and tertiary amines.

The bond angle in methane (CH4) is approximately 109.5 degrees due to its tetrahedral geometry.

Bulk modulus (K) = -ΔP / (ΔV/V) = 1000 kPa / (0.01 m³ / 1 m³) = 100000 kPa.

Bulk modulus (K) = -ΔP / (ΔV/V) = 50 MPa / (0.02 m³ / 1 m³) = 2500 MPa.

Bulk modulus (K) = -ΔP / (ΔV/V) = -50 MPa / (-0.002 m³ / 1 m³) = 25000 MPa = 25 GPa.

C = Q/V = 10 × 10^-6 C / 5 V = 2 × 10^-6 F = 2 µF.

The capacitance of a spherical capacitor is given by C = 4πε₀ab/(b-a).

Capacitive reactance Xc = 1 / (2πfC) = 1 / (2π * 60 * 10e-6) = 265.26Ω.

Xc = 1 / (2πfC) = 1 / (2π × 50 × 10 × 10^-6) = 318.31 ohms.
