11. What is the charge of an up quark? b. -e d. +e a. C. 12. Which of the following shows the quark composition of baryon? a udd b. udu c. uud d. duu 13. Which observer in the figure below sees the ball's correct path? (a) (b) Figure 39.1 (a) The observer in the truck sees the ball move in a vertical path when thrown upward, (b) The Earth observer sees the path of the ball as a parabola. a. The observer in the truck c. both observer b. The observer in the ground d. none of the above 14. You are observing a spacecraft moving away from you. You measure to be shorter than when it was at rest on the ground next to you. You also see a clock through the spacecraft window, and you observe that the passage of time on the clock is measured to be slower than that of the watch on your wrist. Compared to when the spacecraft was on the ground, what do you measure if the spacecraft turns around and comes toward you at the same speed? a. The spacecraft is measured to be longer and the clock runs faster b. The spacecraft is measured to be longer and the clock runs slower c. The spacecraft is measured to be shorter and the clock runs faster d. The spacecraft is measured to be shorter and the clock runs slower 15. How long will an ice cube wrapped by a blanket remain frozen? a. a shorter length of time b. a longer length of time c. the same length of time d. alonger length of time than an ice cube exposed to air at room temperature 11.
