In 2019, the Budgetary allocation to the Pradhan Mantri Gram Sadak Yojana was Rs 19,000 Crores.

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.

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.

The objects through which light cannot pass are called as Opaque objects. Some objects allow some light to pass through them and are called as Translucent objects. The objects which allow all the light to pass through them are called as Transparent objects.

Here in the given options Book is an example of opaque object as it does not allow light to pass through it. Water is transparent object and notebook paper and sun glasses are examples of translucent objects.

The world's largest weapons importer is Saudi Arabia.

Himachal Pradesh state became 1st to launch a pan-India single emergency no. 112 where all kinds of immediate help can be sought in urgent matters.

Under this project, an Emergency Response Centre (ERC) has been established in Shimla along with 12 district command centres (DCCs), covering the entire state. The ERC has been integrated with police (100), fire (101), health (108) and women (1090) helpline numbers to provide emergency services through the emergency number '112'.
