Distance between two points

Distance between two point (8, -4) and (0, a) is 10 . All the values are in the same unit of length. Find the positive value of a.

The actual length covered by a moving body in between two points irrespective of the direction in which the body is moving is called distance displacement is the shrtest distance between two points The units of both distance and displacement are metre and centimeter In the above question, what is the distance travelled by the man?

The actual length covered by a moving body in between two points irrespective of the direction in which the body is moving is called distance displacement is the shrtest distance between two points The units of both distance and displacement are metre and centimeter If a body completes one complete revolution in a circular path, then

The distance between two point sources of light is 24cm. Find out where would you place a converging lens of focal length 9cm, so that the images of both the sources are formed at the same point.

The semi vertical angle of the cone of the rays of light incident on the objective of a microscope is 20^(@) . If the wavelength of incident light is 6000Å , calculate the smallest distance between two points which can be just resolved.

A telescope of aperture diameter 5m is used to observe the moon from the earth. Distance between the moon and earth is 4 xx 10^5 km. Determine the minimum distance between two points on the moon's surface which can be resolved using this telescope. (Wave length of light is 5893 A^@ .

The distance between two points (A and B is 110 km. X starts running from point A at a speed of 60 km/hr and Y starts running from point Bat a speed of 50 km/hr at the same time. They meet at a point C, somewhere on the line AB. What is the ratio of AC to BC?

Two identical coherent sources produce a zero order bright fringe on a screen. If beta is the band width, the minimum distance between two points on either side of the bright where the intensity is half that of maximum intensity is half of maximum intensity is
