i think its a or b
Which scenario describes periodic behavior?
A pendulum swinging back and forth
A ball bouncing up and down on the ground
The takeoff and landing of a jet plane
The path a dolphin swims in the ocean
Both a and b are not truly periodic, since the oscillation gradually has lower and lower amplitude.
But, all other things being equal, I'd say the pendulum keeps its amplitude much better than the ball, so I'd have to go with (a)
Even (c), if the plane is always on time. <lol>
The answer is only : A pendulum swinging back and forth.
It cannot be the other options because when looking for a period behavior, we are also looking for something to come back to the initial starting point. Can't be the ball because logically it would eventually come to a stop. Can't be a plane because it is going from one location to another and will eventually stop. It can't be the dolphin because the dolphin will continue on swimming it the same direction and will not return to the initial start.
nvm i think i got this one
To determine which scenario describes periodic behavior among the given options, let's first understand what periodic behavior means. Periodic behavior refers to a pattern or motion that occurs at regular intervals, repeating itself over time.
Now, let's consider each option:
A) A pendulum swinging back and forth: Yes, this scenario describes periodic behavior. The pendulum swings back and forth between two extreme points, completing one cycle repeatedly.
B) A ball bouncing up and down on the ground: Yes, this scenario also describes periodic behavior. The ball bounces up and down, with each bounce following a regular pattern and repeating over time.
C) The takeoff and landing of a jet plane: No, this scenario does not describe periodic behavior. The takeoff and landing of a jet plane does not occur at regular intervals, and it does not repeat itself in a predictable pattern.
D) The path a dolphin swims in the ocean: No, this scenario does not describe periodic behavior either. The path a dolphin swims in the ocean may vary and is not expected to repeat in a regular pattern.
Based on this analysis, options A and B, the pendulum swinging back and forth and the ball bouncing up and down, both describe periodic behavior.
