Question

Event A occurs at spacetime coordinates (300 m, 2 s)

a. Event B occurs at spacetime coordinates (1200 m, 6 μs). Could A possibly be the cause of B? Explain.

b. Event C occurs at spacetime coordinates (2400 m, 8 μs). Could A possibly be the cause of C? Explain.

Short answer

The expression to be used:

Step-by-step solution

Part (a) Step 1: Given information

We have been give the space time coordinates of Event A and B as (300 m, 2 s) and (1200 m, 6 μs) respectively.

Part (a) Step 2: Explanation:

A is the cause of B.

$v$=$\frac{∆x}{∆t}$=$\frac{900m}{4\mu s}$=225m/μs < c.

Part (b) Step 1: Given information,

Spacetime coordinates of Event C are given as (2400 m, 8 μs)

Part (b) Step 2: Explanation: 

No A isn't the cause of B.
