The spaceship intergalactica lands on the surface of the uninhabited pink planet, which orbits a rather average star in the distant garbanzo galaxy. a scouting party sets out to explore. the party\'s leader–a physicist, naturally–immediately makes a determination of the acceleration due to gravity on the pink planet\'s surface by means of a simple pendulum of length 1.26 m. she sets the pendulum swinging, and her collaborators carefully count 105 complete cycles of oscillation during 202 s. what is the result?
