The rate of change of velocity is called as Acceleration.

Arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation (usually veins carry deoxygenated blood to the heart but the pulmonary veins carry oxygenated blood as well).

Enid Mary Blyton was the English children's writer published 59 new books in 1955.

Garbage burning is common in rural areas, but it poses health concerns and hazards to the environment. It especially affects people with sensitive respiratory systems, as well as children and the elderly.

Benefits ::

• It produces methane that can be used like natural gas.
• It partially addresses the solid waste disposal problem.
• It provides biomass energy.

Hence, it creates more space for farming is not the benefit of the burning garbage.

Bilater monopoly occurs in a market where a single seller i.e, a only one monopoly and a single buyer i.e, one monopsony exists.

German Chemist, Adolf von Baeyer first synthesized Barbituric Acid in 1864.

Polarity :: 

The polarity of a molecule defines its other physical properties such as melting point, boiling point, surface tension, vapor pressure etc... Simply, polarity occurs when the electron distribution in a molecule is asymmetric. This results in a net dipole moment in the molecule. One end of the molecule is charged negative while the other gets a positive charge.

The polarization of a molecule greatly depends on the shape of the molecule. A diatomic molecule like HF mentioned above has no issue of shape. The net dipole moment is only due to the uneven distribution of electrons between the two atoms. However, when there are more than two atoms involved in making a bond, there are many complexities.

The water molecule is of bent shape. Therefore, when the two pair of electrons shared by oxygen with two hydrogen atoms is pulled towards oxygen, the net dipole moment results in the direction of the oxygen atom. There is no other force to cancel out the resultant dipole moment. Hence, the water molecule is highly polar.

Ammonia molecule is of a pyramid shape and the electronegative N atom pulls the electrons towards itself. The three N-H bonds are not in the same plane; hence the dipole moments created do not get canceled out. This makes ammonia a polar molecule.

However, the dipole moments sometimes get canceled due to the shape of the molecules, making the molecule non-polar. Carbon dioxide is such a molecule.
