A position-time graph is shown below:
A Speed versus Time graph is shown with y-axis labeled speed in centimeters per second up to 15 and x-axis labeled time in seconds up to 10. A straight line connects the points 0, 0 and 3, 3. A horizontal line connects points 3, 3 and 6, 3. A straight line connects 6, 3 and 10, 11.
Which statement accurately describes the motion of the object in the graph above over 10 seconds?
The object moves forward at 1 cm/s, stops, and then continues at the same velocity.
The object moves forward at 1 cm/s, stops, and then increases velocity to 2 cm/s.
The object is at rest for 4 seconds and then moves forward for 4 seconds at 1 cm/s.
The object is at rest for 3 seconds and then decreases velocity to 1 cm/s for 3 seconds.

I'm thinking it's 2 you are asked to explain the earth's magnetic field. which is the best reply? 1. the earth's magnetic south is similar to the north pole of a magnet. 2. the earth's core has a strong magnetic charge similar to the south pole of a magnet. 3. the earth's geomagnetic south is similar to the south pole of a magnet. 4. the earth's magnetic charge is not centered at either pole; it varies based on location.
