Question 9 A ball is dropped with an initial velocity $v_0 = 0$ m/s at a time $t = 0$. What will be the position of the ball in a time 7.34 s? (use $g = -9.8$ m/s$^2$ and take $y = 0$ to be the point from where the ball is dropped).

Question 1 Genetic testing of 556 plants sampled from a population of blackberries generated the following results at a single locus: Genotype Number observed A1 A1 99 A1 A2 206 A2 A2 251 a) What are the frequencies of the two alleles in the population? b) Test whether the plant population is in Hardy-Weinberg equilibrium. Question 2 The ability to taste phenylthiocarbamide (PTC) in humans is controlled by a dominant allele (T). The recessive allele (t) occurs at a frequency of 0.2 in the population. In a population of 1 million people, how many people would you expect: a) to not be able to taste PTC b) to be carriers for the recessive allele c) to be “true-breeding” for the ability to taste PTC

When an electron moves up to higher energy levels, the atom emits a photon of light whereas the atom absorbs a photon of light when an electron drops to a lower energy level. The photons emitted from an atom appear as a line spectrum.

Part 2: Angled Launch - By loosening the support screws, adjust the orientation of the launcher to some launch angle between 25° and 55°. Record your launch angle $\theta$ = ____ (If not doing experiment use 25°) 5. Calculate both the x and y components of the initial velocity for this new case. 6. Use one of the constant acceleration equations, calculate the vertical velocity that the ball will have just before it hits the surface of the table. Remember that if you take the square root of a number you need to consider whether the positive or negative root should be used. 7. Use this information to calculate how long it will take the ball to fall to the surface of the table. 8. Calculate the horizontal distance that the ball will fly before it hits the table.
