Essential Biological Macromolecules

Properties: Hydrophilic vs. Hydrophobic

• Hydrophilic (water-loving): Nucleic Acids, Carbohydrates, Starch, Chitin. Glucose is hydrophilic because it contains many hydroxyl functional groups.
• Hydrophobic (water-fearing): Lipids.

Key Molecules and Building Blocks

• Organic Molecules: Examples include Methane (CH4) and Glucose.
• Creating Polymers: Polymers are created from monomers through a Dehydration Reaction.

Types of Macromolecules

Carbohydrates

• Monosaccharides: Simple sugars like glucose, fructose, and galactose.
• Disaccharides: Maltose is formed from two glucose molecules.

Lipids

• Unsaturated Fats & Oils: These contain carbon-carbon double bonds in their fatty acids.

Proteins

• Proteins are unique in that they contain

Electrostatics and Resistance Solved Problems

Point of Zero Electric Field Intensity

Vicinity Equal to Zero:
Q₁ = -20 × 10^-6 C, Q₂ = +5 × 10^-6 C, r = 2 m
r₁ = (2 + x) m, r₂ = x m

The electric field intensity at P due to Q₁:

E₁ = (1 / 4πε₀) × (Q₁ / r₁²)
= (9 × 10⁹ × 20 × 10^-6) / (2 + x)²

The electric field intensity at P due to Q₂:

E₂ = (1 / 4πε₀) × (Q₂ / r₂²)
= (9 × 10⁹ × 5 × 10^-6) / x²

At P, E = 0, therefore E₁ = E₂:

(9 × 10⁹ × 20 × 10^-6) / (2 + x)² = (9 × 10⁹ × 5 × 10^-6) / x²

4 / (2 + x)² = 1 / x²

(2 / (2 + x))² = (1 / x)²

2x = 2 + x

x = 2 m

Electric Properties of a Uranium Nucleus

Uranium:
e = 1.6 × 10^-19 C, r = 10^-10 m

Q = 9.2e
= 9.2 × (1.6 × 10^-19 C)
= 14.72 × 10^-19 C

(i) Electric Field (E):
E = (1 / 4πε₀) × (Q / r²)
= (9 ×... Continue reading "Physics Solved Problems: Electrostatics and Resistance" »
