6 :: An object is placed upright on the axis of a thin convex lens at a distance of four focal lengths (4 f) from the center of the lens. An inverted image appears at a distance of 4/3 f on the other side of the lens. What is the ratio of the height of the image to the height of the object?
28.
1. 1/3
2. 3/4
3. 4/3
4. 3/1
Answer: A
Explanation: The ratio of object to image distance equals the ratio of object to image height. The ratio of image to object height is found by rearranging the ratios to give 4f /(4/3)f = 1/3. The image is demagnified by a factor of 3. Thus, answer choice A is the best answer.

7 :: Which of the following must be known in order to determine the power output of an automobile?
1. Final velocity and height
2. Mass and amount of work performed
3. Force exerted and distance of motion
4. Work performed and elapsed time of work
Answer: D
Explanation: Power is defined as the rate of doing work. For the automobile, the power output is the amount of work done (overcoming friction) divided by the length of time in which the work was done. Therefore, answer choice D is the best answer

8 :: A 15.0-eV photon collides with and ionizes a hydrogen atom. If the atom was originally in the ground state (ionization potential =13.6 eV), what is the kinetic energy of the ejected electron?
1. 1.4 eV
2. 13.6 eV
3. 15.0 eV
4. 28.6 eV
Answer:
Explanation: Conservation of energy requires that the 15.0 eV photon energy first provides the ionization energy to unbind the electron, and then allows any excess energy to become the electron's kinetic energy. The kinetic energy is this case is 15.0 eV-13.6 eV = 1.4 eV. Thus the correct answer is A.

11 :: Based on the passage, the mutation in the DNA in affected males from Family 2 most likely results in:
1. the replacement of a single amino acid in Protein R.
2. the replacement of a single amino acid in Protein P.
3. the introduction of a premature stop codon in Protein R.
4. the introduction of a premature stop codon in Hormone X.
Answer: B
Explanation: According to statement 5, Protein P from affected males from Family 2 could not be phosphorylated.This means that the genetic defect in Family 2 must be in the gene that codes for Protein P.Therefore, the correct answer choice is B, that the alteration of one amino acid in Protein P is the likely result of the mutation in the DNA of affected males.
