A seconds pendulum is a pendulum whose period is precisely two seconds i.e, one second for a swing in one direction and one second for the return swing.

All the data in a computer system consists of binary information. 'Binary' means there are only 2 possible values: 0 and 1.

Computer software translates the information you actually give on it such as decimal numbers, text, photos, sound, and video to the binary information.

Original jurisdiction means that the court has the right to hear the case firsthand while appellate jurisdiction means that the court will hear an appeal that came from a court of original jurisdiction.

In terms of jurisdiction, the Supreme Court has Original jurisdiction and appellate jurisdiction.

Heat from the sun travels in the form of rays and are called as heat rays. This heat is called as radiation.

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.

Frankenstein is an English Novel by Mary Shelley. In Frankenstein, Victor is a character who changes from an optimistic, eager young man to one who is anxious and Remorseful.
