why a hare runs in zig zag motion for the escape

Evidence for Particulate Nature of Matter From Brownian Motion - When we look at a glass of still water on the table, it seems incredible that millions of molecules are moving about restlessly inside it. A British botanist called Robert Brown, however, discovered evidence of this movement..

When we look at a glass of still water on the table, it seems incredible that millions of molecules are moving about restlessly inside it. A British botanist called Robert Brown, however, discovered evidence of this movement over 200 years ago. He was observing through a microscope some very tiny ..

In the example discussed under the topic uniform and non-uniform motion we have classified motion along circular track as an example of non-uniform motion. Let us now see why circular motion is considered as non-uniform motion. The figure ..

In a cricket match a fielder moves his arms back while trying to catch a cricket ball because if he tries to stop the fast moving ball suddenly then the speed decreases to zero in a very short time. Therefore the retardation of the ball will be very large. As a result the fielder has to apply a lar..

When a colloidal solution is viewed through a powerful microscope, the colloidal particles can be seen moving in a random zig-zag path. This zig-zag motion of colloidal particles is called Brownian movement. This random motion is due to collisions between the..

Brownian movement was first discovered by Robert Brown, a botanist, in 1827. He observed that pollen grains in water do not remain at rest but move about continuously and randomly. This random continuous movement (Brownian motion) was observed in colloidal sol when the sol was viewed und..

This is a left handed helix. It has 12 base pairs per turn. The strands in this form move in a 'zig-zag' manner and hence it is called as Z-DN..

Hydrogen Fluoride (HF) In the solid state, hydrogen fluoride consists of long zig-zag chains of molecules associated together through hydrogen bonds. Hydrogen fluoride molecule is represented as (HF) n . With fluorine, the hydrogen bond is so strong that HF molecules remain a..

Question: The path of a free electron in a metal is ___________. 1. parabolic 2. circular 3. a straight line 4. zig zag Answer: ..

In hydrogen fluoride, hydrogen atom is bonded to highly electronegative atom, fluorine (electronegativity = 4). It has been found that in solid state hydrogen fluoride consists of long zig-zag chains of H-F molecules associated by H-bonds. On heating, progressively, the length of the cha..
