Newton's First Law of Motion, or the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force. This principle is still highly relevant today, impacting everyday life in numerous ways. For example, in modern transportation, the law of inertia explains why passengers in a car lurch forward when the vehicle suddenly stops. This understanding has led to the development of advanced safety features like seat belts and airbags, which help protect passengers by counteracting the effects of inertia during sudden stops or collisions. Additionally, the concept of inertia is crucial in sports, where athletes use it to their advantage in activities like running and cycling, maintaining momentum to achieve better performance. Newton's laws continue to underpin much of our understanding of motion and safety in today's world, making them as relevant now as they were centuries ago.

DNA is extracted from unidentified human remains. Because the DNA is degraded, it only produces a profile at two loci: D2S441 (19, 19) and D3S1358 (16, 17). A putative biological parent has the same genotypes at these two loci. Assuming no linkage between these loci and negligible inbreeding in the population, calculate a likelihood ratio for each locus and both loci combined that addresses the following propositions: H1: The two DNA donors are parent/child H2: The two DNA donors are unrelated members of the population Allele frequencies in the population are as follows: Allele D2S441 D3S1358 16 0.031167 0.252857 17 0.205234 0.194843 19 0.11232 0.012599

A very long, straight wire carrying current $i(t)$ and a rectangular single-turn coil lie in the same plane, as illustrated in the figure below. The wire and the coil are surrounded by air. (Figure 1) Determine the rms value of voltage $v_{ab}(t)$ induced in the coil, given that $i(t)$ is a 14-A rms 60-Hz sinusoid, $l$ = 10 cm, $r_1$ = 1 cm, and $r_2$ = 10 cm. Express your answer to four significant figures and include the appropriate units.
