Study the velocity vs. time graph shown. A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 6, velocity in meters per second on the y axis, numbered 0 to 9. A line starts at (0, 2) and ends at (6, 8).
What is the displacement of the object from 2 seconds to 6 seconds?

4 m
8 m
16 m
24 m

Which of the following is a source of heat for magma formation? magma plumes in the continental crust friction due to divergence friction due to subduction magma plumes in the oceanic crust

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.
