Subject: The Problem of Severe Water Crisis Looming Large in India
Sir:
I am writing to your esteemed self to draw people and authorities’ attention towards the ever worsening problem of water shortage across the nation. Owing to so many factors water scarcity problem has become quite serious. The water supply in South India, Maharashtra, M.P., Delhi, U.P., etc. has fallen to minimum level. It is feared by 2020 the water tables underground will run dry.
There is need of changing our attitude towards water conservation. People should not waste water at all. They should use it sagaciously and like a rare commodity. Apart from this the Government should also address the problem at the base level. Proper afforestation around the city, especially along the rivers and canals should be done.
All the water resources in the country should be interlinked. Flood water-management by channeling it to water-shortage areas should be done. The sea water should be converted into potable water in coastal areas. This expertise can be sought from Israel.
The Government should also make strict laws to conserve water and environment. People should be involved in water preservation and conservation campaigns. Without people’s participation water scarcity problem can’t be solved. I appeal to you to publish my views in your reputed daily. I also appeal to people and concerned authorities to look into the matter and shoulder their responsibilities in solving the problem. Thanking you.
Yours truly,
Shalini

Types of movements
There are various types of movement in body parts which can be divided in four types i.e. gliding & angular movements, circumduction & rotation and few other movements.
Gliding movements: Gliding movements is the simplest kind of movement that can take place in a joint, one surface gliding or moving over another without any angular or rotator movement.
Angular movement: Angular movement occurs between long bones. By angular movement the angle between the two bones increased or decreased. The various movements which fall under angular movements are described below:
a) Flexion: Bending parts at a joint so that the angle between them decreases and parts come closer together (bending the lower limb at the knee).
b) Extensions: Straightening parts so that the angle between them increases and parts moves farther apart (straightening the lower limb at the knee).
c) Abduction means moving a part away from the midline (lifting the upper limb horizontally to form a right angle with the side of the body))
d) Adduction means moving a part towards the midline ( returning the upper limb from the horizontal position to the side of the body).
Circumduction: Circumduction is that movement which takes place between the head of a bone and its articular cavity. This kind of motion is best seen in the shoulder and hip joints.
Rotation: Rotation is a form of movement in which a bone moves around a central axis without undergoing any displacement from the axis. Moving a part around an axis is called rotation.eg. Twisting the head from side to side.

<font style="margin:0px; padding:0px; box-sizing:inherit">The molar mass is the mass of one mole (or 6.023 X 1023) particles of that substance. </font><font style="margin:0px; padding:0px; box-sizing:inherit; font-size:13px; font-family:Lato, sans-serif; line-height:18px; color:#696969">The molar mass of an element is equal to the numerical value of the atomic mass. However, in case of molar mass, the units change from ‘u’ to ‘g’. The molar mass of an atom is also known as gram atomic mass.
For example mass of 6.023 X 1023 atoms of sodium or molar mass of sodium is 23g, but its atomic mass is 23u</font>
Calculation of molar mass: The molar mass of oxygen is equal to mass of one mole of oxygen. Oxygen forms a divalent molecule, so this is the mass of one mole of O<font style="margin:0px; padding:0px; box-sizing:inherit; font-size:9pt">2</font>.
Atomic weight of oxygen atom = 16g
Molar mass of oxygen = 2 x 16.00 g = 32.00 g
Molar mass of a molecule: Molar mass of a molecule is the mass of 1 mole of molecule.
To find the molar mass of a molecule we should add the atomic masses of all the atoms present in that molecule.
The molar mass of water is the mass of one mole of H2O.
Now add the atomic masses of the atoms of hydrogen and oxygen in a molecule of water
= 2 x 1.008 g+ 1 x 16.00 g = 18.02 g
