A body of mass m  is tied to one end of spring and whirled round in a horizontal plane with a constant angular velocity. The elongation in the spring is one centimeter. If the angular velocity is doubted, the elongation in the spring is 5 cm. The original length of spring is..

Let n be the number of points having rational coordinates equidistant from the point

Both sickle cell anemia and Hunington’s chorea are :

A very much publicised treatment method ‘DOTS’ is being adopted for the cure of

Sickle cell anaemia is due to

In figure, and then the area of the shaded region in square units is

In the figure, and ar The value of ?

The median AD of the triangle ABC is bisected at E and BE meets AC at F. If AF:AC =1/k then the value k

In the figure, If AB = 6 cm, BE = 4cm, CD = 10cm, then EF + EC = ... Cm.

In the figure, , AB = 9cm, AD = 7cm, CD = 8cm and CE = 10cm Then DE = ?

In the figure, If AB = 3cm, PB = 2cm and PR = 6cm then QR = ? cm.

In the figure, and If OA = 3x – 1, OB = 2x + 1, OC = 5x – 3, OD = 6x – 5 then AC =....units.

Hence AC=12

Two line segments and intersect at E such that If AE = 4cm, BE = 3cm, CE=6cm and DE = x cm then x = ?

Hence x=2
