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".
what is the equation for work
Two kilograms of an ideal gas with constant c p =1kJ/kgK and c v = 0.7kJ/kgK are contained in an insulated piston-cylinder device with an initial volume of 0.3m 3 and a pressure o
FORCE ON THE PARTICLE: For a mass m to have acceleration, a force given by F = ma is always required. In uniform circular motion, acceleration is of value v2/t and is directed tend
Determine the HVL of photons in air, water, muscle, bone, and Pb for energies of 5 keV, 100 keV, 1 Mev and 100 MeV and then fill in the table below. Note that you must find the HVL
A quarter of a wavelength is equal to how many degrees of phase? A quarter of wavelength is equaivalent to 90 degrees of phase.
Explain the Energy and Power in Circuits Electrical power dissipated in a circuit or a single circuit element can be calculated using P = I V where power (P) is in wa

A galaxy in the constellation UrsaMajor is receding from the earth at 15,000 km/s. If one of the characteristic wavelengths of the light the galaxy emits is 550 nm, what is the cor
An elevator is stopped at the ground floor. It starts moving upwards at constant acceleration a>0 for 5 seconds. It then keeps a constant speed for 35 seconds. Finally, it slows do
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
