A Particle (Charge = 50 μC) Moves in a Region

question 11

Multiple Choice

A particle (charge = 50 μC) moves in a region where the only force on it is an electric force. As the particle moves 25 cm from point A to point B, its kinetic energy increases by 1.5 mJ. Determine the electric potential difference, V_B − V_A.

• A) −50 V
• B) −40 V
• C) −30 V
• D) −60 V
• E) +15 V

Definitions:

Natural Selection

The evolutionary process by which organisms better adapted to their environment tend to survive and produce more offspring.

Behavioral Phenotypes

Observable characteristics or behaviors that result from the interaction of genotype and environment.

Canalized

A process by which the genetic development of an organism is guided by the environment so that a certain phenotype is produced regardless of variability in the environment or genetics.

Niche Construction

The process by which organisms alter their own and each other’s environments, potentially affecting both their own evolution and that of other species.
