the question is simply asking you to find the circumference of the circle. the formula for the circumference of a circle is c = Pi x d (d - diameter...in your case you have the radius and therefore the formula you want to use is c = Pi x 2r (r = radius).

What is the displacement of a person when he covers 0.5 the distance in a circular path of radius 5 meter?

If he covers 1/2 the length of the circular path, then the beginning and end of histrip are at opposite ends of a diameter of the circle.Diameter = 2 x radius = 2 x 5 = 10 meters.


When can a body have same distance and same displacement?

Distance is equal to magnitude of displacement when the motion is in a straight line.


Why displacement across a circular path is zero if an arthelete covers the distance 2 pie r?

"Distance" is how far you walked or drove from the time you start out untilthe time you stop, regardless of where the places are."Displacement" is the length of the straight line between the place you start fromand the place where you stop, regardless of the path you follow to get there.If you end up where you started, then the displacement is zero.


What is the difference between displacement and speed?

Displacement is the change in position of an object from its initial point to its final point, regardless of the path taken. Speed, on the other hand, is the rate at which an object covers distance; it is a scalar quantity that does not consider direction.


In what instance, if any , the speed and velocity, and distance and displacement means the same?

Just as distance and displacement have distinctly different meanings), so do speed and velocity. Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance.


What is the name of the rate at which an object covers distance in a particular direction?

The rate at which an object covers distance in a particular direction is called velocity. Velocity includes both the speed of an object and the direction of its motion.


Is it possible that the displacement is zero but not the distance?

Yes it is possible consider the case of simple pendulum,its bob tends to vibrate or oscillate with respect to the mean position.Considering one complete of its oscillation when the bob starts its journey from first extreme position then it goes to the mean position but due to inertia(tendency to retain initial state of motion) it does not stop at the mean position and continue to move towards the second extreme position and form the second extreme position it goes back to the mean position and similarly due to inertia it goes back to its first extreme position, in this way one complete oscillation is achieved. So with respect to 'one complete oscillation' the 'net displacement of bob is zero' as it returns to 'same position' from where it has 'started its journey' but the 'net distance is not zero' in this case. Another example of this case can be the movement of car in a circular track, lets say a car started to move from the position A in circular track and after the course of its journey through the track it comes back to position A so there is no net change in position of the car,again displacement is zero but distance is not zero.


Why dispacement can be negative?

When a body covers a displacement in the opposite direction of our reference direction then displacement will be negative.


What is the area of the base of a fountain if the distance from the center of the fountain to the edge is 10 feet?

If the fountain is square, then the base covers 400 square feet of ground. If the fountain is circular, then the base covers 314.2 square feet of ground. (rounded)


An athlete completes one round of a circular track of diameter 200m in 40 seconds What will be the difference covered and the displacement at the end of 2 minutes 20 seconds?

Athlete covers 2pi radians in 40 s. So angular velocity = pi / 20 rad/s Hence the velocity = r w r = 100 m. So v = 5 pi m/s Hence the distance covered in 2 min 20 s ie 140 s = 700 pi metre. Displacement is the shortest distance between initial and final position In 140 s, 3 full rotation and one half rotation. So the he will be diametrically opposite. Hence the displacement is equal to 200 m ie diameter of the circular track.


How does acceleration affect displacement?

If a body travels at a constant speed it will travel a certain distance (doesn't matter how far for our purposes). If it's accelerating then its speed is constantly increasing and therefore it covers more distance over every increment of time that it would if it were moving at its initial speed. So, acceleration increases displacement.


A athlete covers 200m in 40 secondsFind Displacament and distance covered at the end of 140 seconds?

Displacement is the direct distance from start to finish (straight line) so we can't determine this from the info given. The speed is 5m/s so after 140s 700m will have been travelled (5m/s x 140s)
