Answer 1

Explanation:

1. no it does not have acceleration
2. the displacement is zero

may I correct

Answer 2

Answer:

1.)A body moving at constant speed in a circular path experiences an acceleration directed towards the centre of the circular path. This acceleration is called a centripetal acceleration and is provided by a centripetal force. The force might be due to gravity, electro-static attraction, the tension is a string etc.

2.)Displacement is a measure of how far you are from your starting point (regardless of what path you took), and in what direction. It’s a vector, so both the magnitude (or big-ness) and direction matter. So going 1 km north of where you started is different from going 1 km south of where you stared, in terms of displacement

Displacement is a measure of how far you are from your starting point (regardless of what path you took), and in what direction. It’s a vector, so both the magnitude (or big-ness) and direction matter. So going 1 km north of where you started is different from going 1 km south of where you stared, in terms of displacementDistance is how far you’ve travelled, regardless of where you started or ended. It’s a scalar quantity, so only the magnitude matters; it has no direction. It’s what a Fitbit tracks when it counts how many steps you’ve taken, which means path patters. So going 1 km north or south of where you started is still just going a distance of 1 km; the direction makes no difference.

Let’s say the distance between A and B is AB.

Let’s say the distance between A and B is AB.In this case, the body’s displacement is clearly 0 since it returns to its starting point A.

Hope it's helpful

And plzzzz mark me as brainlist

for all my answer that I given to you plzzz
