Newton has given three laws to describe the motion of bodies. These laws are known as Newton’s laws of motion. Newton's laws of motion give a precise definition of force and establish a relationship between the force applied on a body and the state of motion acquired by it.

True, the speed of the object is a scalar Quantity

No. When the body comes back to the same position after traveling a distance, its displacement is zero though it has traveled some distance.
Newton used the third law of Kepler to calculate the gravitational force of attraction. So, what are Kepler’s laws? Johannes Kepler derived three laws, which govern the motion of planets, called Kepler's laws. These are: The orbit of a planet is an ellipse with the Sun at one of the foci. This law is also known as the 'law of orbits'. The line joining the planet and the Sun sweep equal areas...

In ground wave propagation, it is a method of radio wave propagation that uses the area between the surface of the earth and the ionosphere for transmission.
The factor on which the maximum range of propagation in ground wave propagation depend are as follows :
The density of ionization of the layer,.
Angle at which it enters the surface.

A chiral center is an atom that has four different groups bonded to it in such a manner that it has a non-superimposable mirror image.
Photolysis refers to the splitting of water using light energy. It occurs during the light reaction in photosynthesis in the chloroplast granum. The mineral ions essential for the process of photolysis of water are manganese, chlorine, and calcium. Besides these, the manganese activates enzyme involved in photosynthesis and nitrogen metabolism, especially in the photolysis of water to release oxygen
Charges on the glass rod are positive, so the charge on gold leaves will also be positive. Due to X-rays, more electrons from leaves will be emitted, so leaves becomes more positive and diverge further.
In the MKS System or SI Units, the absolute unit of work is joule (J).  In the CGS system, the absolute unit of work is erg.
A Galvanometer is an instrument that can measure the small electrical current by deflection in the electrical circuit. It can be referred to as the electromechanical instrument that is used to detect or indicate the electric current. A Galvanometer can work as the actuator, by producing the rotary deflection of any "pointer", in response to the electric current that is flowing through the coil...
Good luck!!

A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications.
