Find the zeroes of the polynomial 3×2-2 and verify the relationship between the zeroes and coefficients.
The temperature of the two outer surfaces of a composite slab, consisting of two materials having coefficients of thermal conductivity K and 2K and thickness x and 4x , respectively, are T2 and T1(T2>T1).The rate of heat transfer through the slab, in a steady state is A(T2−T1)Kxf, with f equal to
Coefficient of real expansion of mercury is 0.18 X 10/-3°C. If the density of mercury at 0°C is 13.6 g/cc, its density at 200°C is
A system consists of three masses m1, m2 and m3 connected by a string passing over a pulley P. The mass m1 hangs freely and m2 and m3 are on a rough horizontal table (the coefficient of friction= μ)The pulley is frictionless and of negligible mass. The downward acceleration of mass m1 is (Assume m1=m2=m3=m
The density of water at 20°C is 998 kg/m3 and at 40°C is 992 kg/m3. The coefficient of volume expansion of water is
