It is a seismograph that would be most useful.
Explanation:
Methane (CH4) is 30 times stronger than carbon dioxide as an absorber of infrared radiation.
I believe the answer would be that the system potential energy will increase; while the Mar's angular momentum will remain the same.
Mars rotates on its axis, completing one revolution every 24.6 hours. The axis of mars is tilted at 25 degrees and 12 minutes relative to its orbital plane about the Sun. This produces seasons on the surfaces of Mars, similar to the seasons on Earth.
Explanation:
Einsteins theory of relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line.
