• W) Mercury at inferior conjunction • X) Venus at opposition • Y) Mars at eastern quadrature • Z) Jupiter at conjunction

4 Earth Science

• 4) EARTH AND SPACE Multiple Choice Which of the following is true of sandstone formed from a long-term paleodesert?

• W) It would exhibit clearly graded bedding • X) It would have preserved ripples but not dunes • Y) It would appear black due to the dark iron-rich

minerals present • Z) It would contain well rounded grains and have

high quartz content

5 Energy

• 12) ENERGY Multiple Choice Which of the following was NOT an effect of removing sulfur from diesel fuel?

• W) It lowered the nitrous oxides and soot emissions • X) It slightly increased gas mileage in diesel engines • Y) It allowed the use of advanced emissions control

systems • Z) It reduced the lubricity of the fuel

6 PhysicsAn indestructible bullet 2.00 cm long is fired straight through a board that is 10.0 cm thick. The bullet strikes the board with a speed of 420 m/s and emerges with a speed of 280 m/s. • (a) What is the average acceleration of the bullet as it

passes through the board? • (b) What is the total time that the bullet is in contact

with the board? • (c) What thickness of board (calculated to 0.1 cm) would

it take to stop the bullet, assuming that the bullet’s acceleration through all parts of the board is the same?

7 Biology
