Answer:
A chair at rest on the floor has two forces acting on it its own weight that pulls it downward and the floor pushing upward on the chair, both of these forces are acting on it but the net force is 0, so the chair remains at rest and its velocity stays at 0.
Answer:
<em>Well, I think the best answer will be is </em><em>1.59 g/mL Good Luck!</em>
The kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf is false. The kinetic energy on the shelf is zero because it is not in action.
Convergent boundaries form earthquakes, which forms mountains and islands.
Answer:
Answer (b)
Explanation:
Acceleration is the rate of change of velocity in time, therefore constant acceleration will be changing velocity in direct proportion to time and will have a linear plot on a velocity/time chart. This eliminates answer (d) which has an increasing acceleration in time
answer (a) has a negative slope so the acceleration would be considered negative
answer (c) has zero slope so acceleration is zero and velocity is constant.
answer (b) has the required positive slope and acceleration
