Question

Note: The lab itself is on WebAssign. This is so you can check your answers during lab without waiting for your lab instructor to check each one. You should do the prelab before lab but do not do the lab itself before lab.


What is c in meters per nanosecond?
m/ns


You "measure" or "observe" two events to occur at the same time, one nearby and one further away. Which one did you actually see first?

the closer one.both at the same time.     the farther-away one.

Our two intrepid relacar drivers are named Pam and Ned. We use these names to make it easy to remember: measurements made by Pam are primed (x^', t^') and those made by Ned are not primed (x, t). v is the velocity of Pam (the other frame of reference) as measured by Ned. What is the interpretation of v^'?

The velocity of Ned as measured by Pam.The velocity of Pam as measured by Ned.     The velocity of Pam as measured by Pam.The velocity of Ned as measured by Ned.

The role of Pam and Ned are played by pink and blue pegs, which you can insert into the model relacars in order to help you discuss the lab with your groupmates. Which is pink and which is blue?

Ned is pink and Pam is blue.It doesn't matter as long as my whole group agrees.     Pam is pink and Ned is blue.
