This is due to the surface tension of water. Because of the surface tension , the drop tends to have minimum possible surface area, and the shape which is possible with minimum surface area is "spherical shape".
Explain the Half-Life The decay of a nucleus is a random event. It is not possible to predict which nucleus will decay and when. Even though over a period of time, the decay

Standard quantum limit: The restriction imposed on standard methods of measurement through the uncertainty principle inside quantum mechanics.
Three impedances are connected in series across a 100V, 2kHz supply. The impedances comprise: (i) An inductance of 0.45mH and 2 resistance, (ii) An inductance of 570µH a
Medicines: 1. Iodine 131 is used for the study of thyroid glands. 2. Radiation in low dosage can also be used for sterilizing bandages. 3. Radio-Cobalt-60 has been widely
A constant potential difference is applied across the plates of a parallel-plate capacitor. Neglecting any edge effects, the electric field inside the capacitor is: a) constan
Balanced and Unbalanced Forces:- Newton's first law of motion states that "an object at rest stays at rest and an object in motion stays in motion with the similar speed and in
what is semi conductor
You pull a simple pendulum of length 0.240 m to the side through an angle of 3.50 degrees and release it. a) How much time does it take the pendulum bob to reach its highest speed?
(i) It having of dissimilar bright lines. (ii) It is given by an excited source in atomic state. (iii)E.g. Spectrum of excited helium, mercury vapours sodium vapours or atomi
The force of attraction between the molecules of water is higher.
Because of surface tension, every thing in the universe wants to achieve stability,they do that by lowereing their energy.which in this case is the surface energy.a sphere offers lowest surface area yet a very large volume
