The number of sides in a decagon is (l+15)/2 . The value of l is

Find the perimeter of a rectangle whose length (l) = 15 cm and breadth (b) = 12 cm .

Calculate entropy change (in joule) for reversible isothermal expansion from 5L to 15L for 2 mol of an ideal gas.

A plano-concave lens is made of glass (R.l. = 1.5) and the radius of curvature of the curved face is 50 cm. The power of the lens is

At 27^(@)C for reaction, C_(6)H_(6)(l)+(15)/(2)O_(2)(g)to6CO_(2)(g)+3H_(2)O(l) proceeds spontaneously because the magnitude of

If 1.5 L of an ideal gas at a apressure of 20 atm expands isothermally and reversibly to a final volume of 15 L, the work done by the gas in L atm is:

An element of length vecDeltal=DeltazhatK is placed at origin and carries a large current l=15A. The magnetic field on the y axis at a distance of 0.75 m is (Deltaz=0.75 cm)
