NASA is conducting a test with the Perseverance Rover to investigate the gravity on Mars. They test a pendulum with a length of L on the Earth and find it has a period of 1.0 S. The Perseverance Rover has a similar pendulum with a length of L/2. If the acceleration due to gravity on Mars is 1/3 the acceleration due to gravity on the Earth what is the period of the Perseverance Rover's pendulum on Mars?

NASA lands Perseverance rover on the Mars surface, carrying the first helicopter for another planet. NASA successfully landed its fifth robotic rover on Mars on Thursday, with the U.S. space agency confirming that Perseverance touched down safely on the red planet's surface.

Explanation:

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
