Areos Practice Exam- Physics 6B
Good Luck- go through all of your notes and try to answer these problems. If I was you, I would write my formula sheet before doing this exam so that when the times comes you will know where all of your equations are.

CHEMISTRY l A PRACTICE PROBLEMS FOR FINAL EXAMINATION
These problems are related only to material covered since the second hour examination. The final examination will cover all of the topics that were discussed this quarter. You should also study t
Q1. An alien spacecraft flies horizontally over your head, at a speed of 0.5c. You see its searchlight blink on for a time tA. The first officer on the spacecraft measures that the searchlight is on for a time tB. Which time is shorter? (A) tA (B) tB
Q37.2. As a high-speed spaceship flies past you at half the speed of light, a strobe light fires at the center of a room aboard the spaceship.
As measured by you, the light from the strobe A. reaches point A before it reaches point B. B. reaches poi
