In a chain reaction uranium atom gets fissioned forming two different material. The total weight of these put together is

A chain reaction in fission of Uranium is possible because

A chain reaction in fission of Uranium is possible because

Two thin sysmmetrical lenses of different nature and of different material have equal raii of curvature R=15cm . The lenses are put close together and immersed in water (mu_(w)=4//3) . The focal length of the system ini water is 30cm. The difference between refractive indices of tthe two lenses is

The ratio of weights of two sphere of different materials is 8:17 and the ratio of weights per 1 cc of materials of each is 289 : 64. The ratio of radii of the two spheres is

Two thin symmetrical lenses of different nature and of different material have equal radii of curvature R = 15 cm . The lenses are put close together and immersed in water (mu_(w) = (4)/(3)) . The focal length of the system in water is 30 cm. The difference between refractive indices of the two lenses is
