Newton's law of universal gravitation states that a particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Protein digesting enzymes are secreted in inactive form to protect the organs and glands from digestion by the enzymes. If they are released in active form, they start digesting the glands carrying them and the site where they are released. Therefore, they are released in inactive form and are activated only when proper condition is maintained such as presence of food and release of HCl.

Aromatic compounds are substances that consist of one or more rings that contain alternating single and double bonds in its chemical structure. In real life, many aromatic compounds have an odor, however, there are some compounds that are chemically aromatic, but do not have a distinct smell.
For example, benzene is an aromatic compound.

The term 'aromatic' is used by chemists for substances with distinct odors. In this lesson, we will learn all about aromatic compounds, the features of such compounds' chemical structures, and Huckel's Rule.
What Are Aromatic Compounds
Take a moment and think of substances that have a strong fragrance. What kind of things come to your mind? Perfume, vanilla or, perhaps, even cinnamon? All of these are fragrant or aromatic. While they certainly smell differently, they do have something in common: these substances are made of aromatic compounds.

First Past the Post System, or otherwise known as Simple Majority System, is an electoral system in which the candidate who gets the maximum number of votes in the elections, gets elected, in a single member constituency. The result is based on the majority of votes obtained by the nominated candidate.
The multi-cornered contest is also experienced, wherein the number of candidates contesting the election rises to 3 or 4 and sometimes even more than 6. In such cases, the candidate getting the highest number of total votes cast, gets the seat, as it follows the simple rule of the majority, even if it is less than 50% of total votes.
It aims at electing a person who can represent the constituency, in the parliament. So, votes are cast by people for different candidates, who are nominated by a political party. Countries like UK, USA, Canada and India follows it.

{tex}\begin{array}{l}\cos x=\frac35\\\sin x=\sqrt{1-\frac9{25}}=\sqrt{\frac{16}9}=\pm\frac45\\\end{array}{/tex}
In 3rd quadrant
sin is -ve so sinx = -4/5
tan is -ve so tanx= -(4/5)/3/5= -4/3
other ratios can be calculated
