`1/10` of a rod is coloured red , `1/20` orange, `1/30` yellow, `1/40` green, `1/50` blue, `1/60` black and the rest is violet. If the length of the violet portion of the rod is `12.08 metres,` then the length of the rod is :

(1)/(10) of a pole is coloure,(1)/(20) white,(1)/(30) blue,(1)/(40) black,(1)/(50) violet,(1)/(60) yellow and the rest is green.if the length of green area of pole is 12.08m, then find the length of pole.

(1)/(10) of a pole is coloured white,(1)/(20) is coloured red,(1)/(30) is coloured green and the rest is coloured black.If the length of the black portion is 14m 70cm,then find the length of the pole.

A steel rod of length 20 3/26 is cut out from a rod of length 56 1/5 . What then is the remaining length of the rod?

A metal rod of diameter 1 cm measures 50 cm in length at 65 °C. If the coefficient of linear expansion of the rod is 16 x 10-6/ °C, the length of the rod at 0 °C will be

A steel rod of length 20 3/26 is cut down from a rod of length 56 1/5 what when is the remaining length of the rod?

A uniform steel rod of length 1m and area of cross section 20 cm^2 is hanging from a fixed support. Find the increase in the length of the rod.

The refractive indices of the material of a lens for violet, yellow and red colours of light are 1.66, 1.64 and 1.62 respectively. The mean focal length of the lens is 10 cm. What is the chromatic aberration of the lens between the violet and the red colours ?

A double convex lens is made of glass which has refractive inded 1.55 for voilet rays and 1.50 for red rays. If the focal length for violet rays is 20 cm, the focal length for red rays will be
