Final answer:
The elapsed time for a process appears longer for an observer moving relative to it, and proper time is measured by an observer moving with the process.
Step-by-step explanation:
The elapsed time for a process does indeed depend on the relative motion of an observer with respect to the process being measured. For an observer moving relative to a process, the elapsed time seems longer due to the effects described by the theory of relativity.
In contrast, for an observer moving with the process, the elapsed time is shorter, this being the proper time measured. These concepts are grounded in the physics of time intervals and their dependence on the motion of the observer.
Intermediate timer events in computer programming allow a process to delay for a specific period of time or until a specific date or time. This means that both option a and option b are true.
For example, if you want a process to delay for 1 day before continuing, you can use an intermediate timer event. Or if you want a process to delay until a specific date and time, you can also use an intermediate timer event.
The correct option is
