A firecracker explodes on the ground in front of Martin just as Lisa passes by at 0.5c. 30 μ,s later, according to Martin, a second firecracker explodes in front of him. Using what you've learned from Figure 27.18, the time Lisa measures between these two events is 

A. 30 μ,s 

B. Greater than 30 μ,s 

C. Less than 30 μ,s

FIGURE 27.18 A moving clock runs slow relative to a stationary one. Event 1: Moving clock passes stationary clock A; all clocks read 0. Event 2: Moving clock passes stationary clock B. Stationary clock A Moving clock Event 1 occurs here. To a stationary observer, event 2 occurs in a different place than event 1, so the stationary clock reads Ar. Note that AAT. To a moving observer,- both events occur at the same place at the center of the cart-so the moving clock reads Ar. Stationary clock B Event 2 occurs here.
