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".
Alpha particles are nuclei of: a) Hydrogen b) Helium c) Oxygen d) Nitrogen Ans: Alpha particles are nuclei of helium.
Ammeter: An electromechanical instrument which is used to calculate the amount of current flowing by an electric circuit is known as an ammeter. It is modified form of a gal

The experimental set-up for producing Newton's ring is shown in fig. (A). A plane-convex lenses L of large radius of curvature with its convexities is placed on a plane glass plate
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
