distance = 1/2 circumference
displacement = 2 r (special case because exactly half of the circle was travelled)
circumference = 2*pi*r
1/2 circumference = 1/2*2*pi*r = pi * r

A cyclist completes a journey of 500 meters in 22seconds part of the way at 10 meter per seconds and the remainder at 50 meter per second how far does she travel at each speed?
Time in Distance 1+ time in distance 2= 22let the 1st Distance be x2nd Distance = 500-xtime = distance / speedx/10 + (500-x)/50= 22LCM = 50multiply equation by 505x+500-x=11004x=600x=150 m150 m at 10m/s350 m at 50m/s
What is the average speed at 20 seconds?
None.Speed is the distance covered per unit of time. If no distance is covered then the speed is 0.None.Speed is the distance covered per unit of time. If no distance is covered then the speed is 0.None.Speed is the distance covered per unit of time. If no distance is covered then the speed is 0.None.Speed is the distance covered per unit of time. If no distance is covered then the speed is 0.
What does Weight x distance equal?
weight x distance = work
Distance equals rt solve for t?
T = Distance/R
What is the distance of 0 to -14 on a number line?
14
What will be the distance and displacement of the body when it completes half a revolution if a body is moving along a circular path of radius R?
wavelength
An athlet completes one round of a circular track of diameter 200m in 40s what will be the distance covered and the displacement at the end of 2 minutes 20s?
Distance covered - 2199m Displacement - 200m Distance covered - 2199m Displacement - 200m
A body is moving along a circular path of radius rwhat will be the distance traveled and displacement of the body when it completes half a revolution?
double of the radius means equal to diameter
What is the circular region of a circle?
the distance around a circular region is called circumference
What is circular diameter?
Circular diameter is the distance from side to side of a circle through the middle.
An athlete completes one round of a circular track of radius 10 meter in 40 sec.the distance covered by him in 2min.20 sec.?
Time=2m and 20 seconds ( converts it into second) s0 time in seconds = 140 seconds now v=w*r = 2*22/7*100 40 seconds = 2 * 22/7 *100 1 second = 2 * 22/7 * 100/40 140 second = 2 * 22/7 * 100/40 * 400 so, it gives = 2200 m so the distnace is 2200 m and the dispalcement is 200 m
Distance through the center of a circular object?
Diameter.
Is distance around a track circumference?
Yes, if it is a circular track.
What is the length of a cylinder?
The perpendicular distance between its circular ends
Explain why the work done of sliding friction is negative when an object undergoes a dispalcement on a rough surface?
Work is done when a force is applied over a distance. If the force acts opposite the direction of motion, like friction, then the work is negative.
Are elliptical orbits circular?
An ellipse is a closed curve that is not circular (the curve is not a constant distance from any point inside of the curve). While some planetary orbits are relatively circular, others are more elliptical, that is having an oval shape with a varying distance from the Sun.
What is the distance around a circular swimming pool that has a 9 foot radius?
56.547
