Question
select two or more answers, for the statements that do not describe the resulting motion of the duck. the duck will stop and then start moving again. the duck will continue moving in its current direction. the duck will move in the direction that the stream is flowing. the duck will stop moving.
To solve this, we analyze the motion of a duck (likely in a stream, though context on initial motion isn't fully given, but using physics principles: if the duck is moving with the stream or has its own motion, we consider which statements are incorrect. A duck in a stream (assuming it's floating or swimming with current) – if no external force stops it abruptly, it won't stop (so "The duck will stop and then start moving again", "The duck will stop moving" are incorrect). Also, if it was moving against or with, but the key is: a duck in a stream (typical scenario) would move with the stream, so "continue current direction" (if current is different) or "stop" / "stop then start" are wrong. Wait, let's re-express:
- "The duck will stop and then start moving again": Incorrect (no reason for stop-start unless force, not typical).
- "The duck will continue moving in its current direction": If the stream is moving, maybe not – but if the duck was moving against, but maybe the question implies the duck is in the stream (so stream's flow is a factor). Wait, maybe the duck is floating: then it moves with the stream. So "continue current direction" (if its current direction was, say, swimming, but if floating, it moves with stream). But the question is which DO NOT describe. Let's think of Newton's first law: an object in motion stays in motion unless force. So:
- "The duck will stop and then start moving again": No force to stop then start, so incorrect.
- "The duck will continue moving in its current direction": If the stream is moving, maybe the duck's current direction (if swimming) vs stream. But maybe the intended answer is that the duck (floating) moves with stream, so "continue current direction" (if its current was, e.g., upstream) would be wrong? Wait, maybe the question is simpler: assume the duck is in a stream, so it moves with the stream. So:
Incorrect statements (DO NOT describe):
- "The duck will stop and then start moving again" (A)
- "The duck will continue moving in its current direction" (B) – wait, no, if the duck was moving in its current direction (e.g., swimming), but stream is moving, maybe not. Wait, maybe the options:
Wait the options are:
- The duck will stop and then start moving again.
- The duck will continue moving in its current direction.
- The duck will move in the direction that the stream is flowing.
- The duck will stop moving.
Assuming the duck is in the stream (floating), then:
- It will move with the stream (so option 3 is correct description).
- So the ones that DO NOT describe:
Option 1: stops then starts – no, unless force, so incorrect.
Option 2: continue current direction – if its current direction was, say, against the stream, but if it's floating, it moves with stream, so "continue current direction" (if current was against) would be wrong. But maybe the question is that the duck is moving with the stream, so "continue current direction" (if its current direction is same as stream) would be correct? No, maybe the intended answer is that the duck (floating) moves with the stream, so:
- "The duck will stop and then start moving again" (incorrect)
- "The duck will continue moving in its current direction" (incorrect? If stream is moving, maybe not)
- "The duck will stop moving" (incorrect)
Wait, maybe the correct non-describing are:
- The duck will stop and then start moving again
- The duck will continue moving in its current direction
- The duck will stop moving
But the question says "select two or more". Let's check typical physics: an object in motion (like a duck in w…
