Answer:

  1. D
  2. B/A

Explanation:

  1. The farther the dots, the faster the object's speed. Assuming that the object goes from right to left, we can clearly see that the dots are getting closer to each other as the object travels to the left, which means that the object is slowing down or decelerating
  2. The motion and speed of the earth's revolution around the sun is constant, therefore both A and B can be used a representation of the earth's motion

What is ticker-tape diagram?

  • Ticker-tape diagram is one a great example of motion diagrams. A stationary "marker/ticker" leaves a mark at the tape at regular time intervals
  • TIcker-tape diagrams can be used for measuring the time it takes an object to travel a distance with unfixed value of speed

How to know if the ticker-tape diagram indicates an accelerating, decelerating or an object moving at constant speed?

  • For an object moving with uniform velocity the marks are spaced uniformly on the tape.
  • For an accelerating object ,the marks are spaced farther away from each other per tick or interval
  • For an decelerating object, the marks gets closer to each other in every tick or interval
