An astronaut measured the surface
gravity of a planet to be 5.77 m/s2. If
its radius is 4.17 x 106 m, what is the
mass of the planet?
?] x 10
kg

Zamir and talia raced through a maze. zamir walked 2 m north, 2 m east, 4 m south, 2 m east, 4 m north, 2 m east, 3 m south, 4 m east and 4 m north. talia walked 2 m north, 6 m east, 3 m south, 4 m east, and 4 m north. compare their displacements: zamir's displacement is talia's displacement.
