Suppose an astronaut drops a feather from 1.2 m above the surface of the moon. if the acceleration due to gravity on the moon is 1.62 m/s2 downward, how long does it take the feather to hit the moon's surface? s

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
