An Alpha Particle (M = 6

question 84

Multiple Choice

An alpha particle (m = 6.7 × 10⁻²⁷ kg, q = +3.2 × 10⁻¹⁹ C) has a speed of 20 km/s at point A and moves to point B where it momentarily stops. Only electric forces act on the particle during this motion. Determine the electric potential difference VA − VB.

• A)+4.2 V
• B)−4.2 V
• C)−9.4 V
• D)+9.4 V
• E)−8.4 V

Lipoproteins

Lipoproteins are particles made of lipids and proteins that transport fats around the body in the blood.

Golgi Apparatus

An organelle found in most eukaryotic cells, involved in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

Proteins and Lipids

Essential biomolecules; proteins are polymers of amino acids functioning in structure and enzymes, while lipids are fatty acids and their derivatives, serving as energy storage and cell membrane components.

Microtubules
