distance &rates

During motion in a straight line, the point object occupies a definite position on the path at each instant. Therefore, to describe the motion, one should specify the length of the path covered by the point object and the instant of time. The length of path covered by the object is the distanc..

One of the main use of trigonometry is to find the distances between points, or the heights of objects, without actually measuring these distances or these heigh..

Distance is a scalar quantity. SI unit of distance is metre.Displacement is the shortest distance covered by a moving object from the point of reference (initial position of the body), in a specified directio..

Distance and Displacement - Suppose a bus starting from a terminus A travels 15000 m to reach terminus B. Then the distance covered by the bus is 15000 m. Now if the bus returns to the terminus A, then what is the distance covered by the bus during the return trip? The..

Suppose a bus starting from a terminus A travels 15000 m to reach terminus B. Then the distance covered by the bus is 15000 m. Now if the bus returns to the terminus A, then what is the distance covered by the bus during the return trip? The distance covered is 15000 m..

The skip distance is the shortest distance from a transmitter, measured along the surface of the Earth, at which a sky wave of fixed frequency (more than f c ) will be returned to Earth. One expects there to be a maximum distance, as limited by the curvature of the Ear..

Heights and Distances..

The height of a building or the width of a river can be measured without climbing or crossing it. In this chapter we will show how it is made possible. Some suitable angles and distances will be measured to achieve the above results. Angle of elevation is the angle between a..

Heights and Distances..

The length of the line segment AB, which joins A (x 1 , y 1 ) and B (x 2 , y 2 ..
