We know that,
1 km = 1000 m
1 hour =3600
Now converting km/h into m/s, we get
90 km/h = 90 km/h x 5/18 = 25m/s.

Coral polyps are short-lived microscopic organisms, which live in colonies. They flourish in shallow, mud free and warm waters. They secrete calcium carbonate. The coral secretion and their skeletons form coral deposits in the form of reefs. They are mainly of three kinds - Barrier reef, Fringing reef and Atolls. The Great Bather Reef of Australia is a good example of the first kind of coral reefs. Atolls are circular or horse shoe-shaped coral reefs.

The property shown by nepthleane and not by sodium chloride is :
Naphthalene undergoes sublimation upon heating and directly changes into vapours. Sodium chloride (common salt) does not undergo sublimation. It melts on strong heating.

At an atmospheric pressure of exactly 760mm Hg (1 atm), the temperature at which a liquid boils is called the normal boiling point of the liquid. For water, the vapour pressure reaches the standard atmospheric pressure of 1 atmosphere at 100°C. So the normal boiling point of water is 100°C (212°F or 373K).

Isotope → Isotopes are atoms with the same number of protons, but differ in numbers of neutrons. Isotopes are different forms of a single element.
Example - Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons.

. The force of gravitation between two objects is inversely proportional to the square of the distance between them therefore the gravity will become four times if distance between them is reduced to half.

A colloid is a kind of solution in which the size of solute particles is intermediate between those in true solutions and those in suspensions.
For Example: - Soap solution, Milk, Ink, Blood and solutions of synthetic detergents.
In a true solution, the solute particles are so small that they cannot scatter or reflect light rays falling on them.
In a colloidal solution (or colloid), the particles are big enough to scatter light.
If a beam of light is put on a colloidal solution kept in a beaker in a dark room, the path of light beam is illuminated and becomes visible when seen from the side.
The path of light beam becomes visible because colloidal particles are big enough to scatter light falling on them in all directions.

In a uniform circular motion the direction of motion keeps on changing with the revolution. With the number of revolution displacement from the initial point to the final point also changes. As both these factors changes velocity also changes. But in that uniform circular motion what remains constant is speed.

The number of particles (atoms, molecules or ions) present in 1 mole of any substance is fixed, with a value of 6.022 × 1023. This is an experimentally obtained value. This number is called the Avogadro Constant or Avogadro Number (represented by N0), named in honour of the Italian scientist, Amedeo Avogadro.1 mole (of anything) = 6.022 × 1023 in number,

Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects. As gravitational force between two object, F∝m1m2r2 thereforce, (i) when mass of one object is doubled, the force become twice. (ii) when distance between the objects is doubled, force become (1/4) of its previous value. when the distance between the 2 objects is halved, the gravitational force between the 2 objects is doubled. when the distance between the 2 objects is doubled then the gravitational force doubles.
