En un t=2s la aceleración de una partícula con un movimiento en contra de las manecillas del reloj, es de \( 6 \mathrm{~m} / \mathrm{si}+4 \mathrm{~m} / \mathrm{sj} \), esta se mueve con velocidad constante. En \( \mathrm{t}=5 \mathrm{~s} \), aceleración es \( 4 \mathrm{~m} / \mathrm{si}-6 \mathrm{~m} / \mathrm{sj} \). Cuál es el radio de la trayectoria tomada por la partícula si t2-t1 es menor que un periodo.

has an absolute advantage in the production of alfalfa, and has an absolute advantage in the production of barley. Jake's opportunity cost of producing 1 bushel of barley is bushels of alfalfa, whereas Latasha's opportunity cost of producing 1 bushel of barley is bushels of alfalfa. Because Jake has a opportunity cost of producing barley than Latasha, comparative advantage in the production of barley, and has a comparative advantage in the production of alfalfa.

The distance that a free-falling object falls is directly proportional to the square of the time it falls (before it hits the ground). If an object fell 72 ft in 3 seconds, how far will it have fallen by the end of 8 seconds? Round your answer to the nearest integer if necessary.

Suppose that a geneticist discovers a new mutation in Drosophila melanogaster that causes the flies to shake and quiver. She calls this mutation quiver, qu, and determines that it is due to an autosomal recessive gene. She wants to determine whether the gene encoding quiver is linked to the recessive gene for vestigial wings, vg. She crosses a fly homozygous for quiver and vestigial traits with a fly homozygous for the wild-type traits, and then uses the resulting F1 females in a testcross. She obtains the flies from this testcross. Phenotype Number of flies vg$^+$ qu$^+$ 230 vg qu 224 vg qu$^+$ 97 vg$^+$ qu 99 Test the hypothesis that the genes quiver and vestigial assort independently by calculating the chi-squared, $X^2$, for this hypothesis. Provide the $X^2$ to one decimal place. $X^2$ = Incorrect
