A drum of 30 cm radius has a capacityof 220 `dm^(3)` of water and is placed on a solid block of exactly the same size as of drum .If a small hole is made at lower end of drum perpendicular to its length, find th horizontal range of water on the ground in the beginning. Given g = 980 cm `s^(2)`.

A drum of 40 cm radius has a capacity of 440 dm^(3) of water. It contains 396 dm^(3) of water and is palece on a solid block of exactly the same size as of drum. If a small hole is made at lower end of the durm perpenduclar to its length , find the horizontal range of water on the ground in the beginning. given g=10 m//s^(2) .

A particle of mass 200g is attached to an ideal string of length 1.30 m whose upper end is fixed to ceiling. The particle is made to revolve in a horizontal circle of radius 50 cm. The tension in the string is (g = 10 m/s^2)

A hollow sphere which has a small hole in its bottom in water to a depth of 30 cm before any water enters in it. If the surface tension of water is 75 dynes/cm then find the radius of the hole in metres (taking g=10m//s^(2))

A solid is in the form of a right circular cone mounted on a hemisphere. The radius of the hemisphere is 3.5cm and the height of the cone is 4cm. The solid is placed in a cylindrical tub, full of water, in such a way that the whole solid is submerged in water. If the radius of the cylinder is 5cm and its height is 10.5cm, find the volume of water left in the cylindrical tub. (U s epi=(22)/7)

A vessel has a small hole at its bottom. If water can be poured into it upto a height of 7 cm without leakage (g=10ms^(-2) ) the radius of the hole is (surface tension of water is 0.7Nm^(-1) )

A horizontal wire 24 cm long falls in the field of flux density 0.8 T. Calculate the emf induced in it at the end of 3s, after it was dropped from rest. Suppose the wire moves perpendicular to its length as well as to magnetic field. Take g=9.8 ms^(-2)

If a vessel has a small hole at the bottom of radius 4 mm, then the rise of water in a vessel without leakage will be (S.T = 72 dyne/cm , g = 1000 "cm/s"^(2) rho = 1 g //cm^(3) )
