Two Very Large Parallel Metal Plates, Separated by 0

question 44

Multiple Choice

Two very large parallel metal plates, separated by 0.20 m, are connected across a 12-V source of potential. An electron is released from rest at a location 0.10 m from the negative plate. When the electron arrives at a distance 0.050 m from the positive plate, how much kinetic energy has the electron gained? (e = 1.60 × 10^-19 C)

• A) 2.4 × 10^-19 J
• B) 4.8 × 10^-19 J
• C) 7.2 × 10^-19 J
• D) 9.6 × 10^-19 J

Definitions:

Codominance

A genetic scenario where two alleles of a gene pair in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Allele

Alternative form of a gene; a gene pair contains two alleles.

Dominant Gene

A gene that expresses its phenotype over another gene (the recessive gene) when the two are present in a heterozygous condition.

Huntington Disease
