A leakproof cylinder of length 1 m, made of a metal which has very low coefficient of expansion, is floating vertically in water at 0∘C such that its height above the water surface is 20 cm. When the temperature of water is increased to 4∘C, the height of the cylinder above the water surface becomes 21 cm. The density of water at T=4∘C, relative to the density at T=0∘C is close to:

1.	A leakproof cylinder of length 1 m, made of a metal which has very low coefficient of expansion, is floating vertically in water at 0∘C such that its height above the water surface is 20 cm. When the temperature of water is increased to 4∘C, the height of the cylinder above the water surface becomes 21 cm. The density of water at T=4∘C, relative to the density at T=0∘C is close to:
Answer» A leakproof cylinder of length $1 m$ , made of a metal which has very low coefficient of expansion, is floating vertically in water at $0^{\circ} C$ such that its height above the water surface is $20 cm$ . When the temperature of water is increased to $4^{\circ} C$ , the height of the cylinder above the water surface becomes $21 cm$ . The density of water at $T = 4^{\circ} C$ , relative to the density at $T = 0^{\circ} C$ is close to:

A parallel-plate capacitor having plate area A and plate separation d is joined to a battery of emf E and internal resistance R at t=0. Consider a plane surface of area A/2, parallel to the plates and situated symmetrically between them. If the displacement current through this surface as a function of time is given as:id=EnRe−tdε0ARWhere, ε0 is the permittivity of free space.The value of n is :
A horizontal curve with superelevation e = 0.05 (note, e=tanβ ) has a posted speed limit of 60 km/h. For this speed limit, only those vehicles with Y/X ratio(in figure) greater than 2 and travelling at speeds greater than 1.2 times the speed limit, will overturn. However, with recent increase in truck traffic the speed limit needs to be modified such that only those vehicles with Y/X ratio greater than 3 and travelling at more than 1.2 times the speed limit will overturn. What should be the new speed limit?(in km/hr round off to integer) (with respect to the figure, assume that the vehicle is travelling into the plane of the paper).50
