PRACTICE EXAM QUESTIONS AND
ANSWERS (VERIFIED AND UPDATED)
Robotic watercraft designed for underwater exploration are referred to as Unmanned Surface
Vehicles (T/F) - ANS False
Scattering is defined as - ANS Beam of radio waves hitting a mass of smaller materials, which
individually reflect and spread the radio waves in different directions
