Bill moved 250 meters west, then turned left and went 300 more meters. Calculate Bill’s distance traveled and displacement from starting position.

there are no correct statementd on the list of choices you provided.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
