Answer:
2.75 meters.
Explanation:
1 meter = 100 centimeters.
There are 275 centimeters.
275/100=2.75
So, each piece of wallpaper was 2.75 meters long.
Answer:
If it falls from 32 feet, how could the distance be 29 feet? Twelve bounces later, 58 is "obviously" incorrect as well. Eliminate those two before you do anything else.
The total distance up until that the nth bounce is
Sn = (32 - 32(.8)12) / (1 - .8) = 149.004883722... = 149

In uniform motion, the path is a straight line, and the object r moving along it at a constant speed.
Answer:
2. The velocity of the particle is tangent to the circle
Explanation:
1. The velocity of the particle is constant.
Incorrect
Reason : Since the tangential speed is not constant, hence the velocity of the particle is not constant.
2. The velocity of the particle is tangent to the circle.
Correct
Reason : In circular motion, the direction of velocity is always given by the tangent to the circle.
3. The acceleration of the particle is constant.
Incorrect
Reason : The tangential speed of the particle is not constant which in turn keeps changing the centripetal acceleration of the particle. hence the acceleration of the particle is not constant.
4. The acceleration of the particle is toward the center of circle.
Incorrect.
