Si en la situación de la figura, la magnitud del campo eléctrico en el punto A es 400 N/C, determine la magnitud del campo eléctrico en el punto B.

Para la configuración de la figura, donde los conductores rectos son muy largos, determine la magnitud del campo magnético (en μT) en el punto P.

En la figura se aprecia un observador “P” viendo una espira conductora circular de radio r constante inmersa en una zona de campo magnético uniforme con la dirección mostrada y cuya magnitud aumenta con el tiempo. Determine el sentido de la corriente inducida en la espira conductora para el observador “P”.

Calcular el valor de una resistencia R (en Ω) si se sabe que cuando la corriente que lo circula disminuye en un 40%, la resistencia debe aumentar en 25 Ω para consumir el mismo voltaje.

Un capacitor de placas paralelas con relleno de aire tiene una capacitancia inicial “C0”. Si aumentamos al triple la distancia entre las placas y reducimos a la tercera parte el área de las mismas, la nueva capacitancia es:

Para el circuito de la figura, determine la magnitud de la corriente a través de la resistencia de 20 W.

Un conductor de gran longitud a través del cual pasa una corriente I ha sido doblado tal como se muestra en la figura. Determine la magnitud del campo magnético neto en el punto O.

Las unidades de la constante dieléctrica relativa de un dieléctrico en el SI son

Genetic counseling problem: These questions are based on your preparation question about inheritance patterns for two genes with disease-associated variants. Information on these human genes and the scenario is provided below. Again, assume, as appropriate, that crossing-over and recombination occur and that all cases of meiosis complete without error. If calculating the rate of recombination, z = distance between genes in base pairs/100,000,000.  Gene name PMP22: Genomic location: Chromosome 17, base pairs 15,229,779 to 15,265,326 Codes for a myelin sheath protein essential to neuron functioning. A variant of the gene is associated with Charcot-Marie-Tooth Disease Type 1A (CMT), which involves impairment of the peripheral nervous system. The degree of symptoms varies and life expectancy is not affected. The disease-causing allele is dominant. Designate alleles as “A” (disease causing, dominant) and “a” (normal, recessive) Gene name BRCA1: Genomic location: Chromosome 17, base pairs 43,044,295 to 43,170,327 Encodes for a protein that helps to monitor DNA damage and acts as a tumor suppressor gene.  Mutations of this gene are associated with a much higher risk of breast cancer. The normal allele shows incomplete dominance, meaning the heterozygote genotype yields a mid-level cancer risk. Designate alleles as “B” and “b”, where “BB” has no increased risk, “Bb” has a mid-level risk, and “bb” has the highest breast cancer risk. As a genetic counselor, you are working with Maurice and Alec, a couple who want to have kids. They have a long-term friend, Marcy, who will carry the baby, and one of them will contribute sperm for intrauterine insemination (IUI).  Both men have a history of breast cancer in their families and both have symptoms of CMT, therefore they are seeking your help to decide who will be the biological parent in order to minimize the chances of passing on deleterious mutations. Here is the genetic information you have for each individual: Marcy has genotype aaBB. Maurice has CMT (with one copy of the disease-causing allele) and one copy of the BRCA1 mutation gene. One of his parents had the genotype AAbb. Alec also has CMT and one copy of the BRCA1 mutation gene. One of his parents did not have CMT but had a high risk of cancer.
