The magnitude of the resultant of two vectors cannot be less than the magnitude of either of those two vectors.
 
  A) True
  B) False

Question 2

A certain unstable particle has a mean lifetime of 1.52  10-6 s. This is the time interval between its creation in a nuclear process and its extinction into decay products, as measured in a frame of reference at rest with respect to the particle.
 
  An average such particle is observed by a scientist on Earth to travel 342 m in its lifetime. What is the speed of the particle relative to Earth? (c = 3.00  108 m/s)
  A) 0.821c
  B) 0.681c
  C) 0.600c
  D) 0.551c
  E) 0.335c
