Circle, ellipse, parabola and hyperbola are curves which are obtained by intersection of a plane and cone in different Ncert Solutions For Class 10th Social Science Journal positions 2. Circle: It is the set of all points in a plane that are equidistant from a fixed point in that plane. Parabola: It is the set of all points in a plane which are equidistant from a fixed point focus and a fixed line in the plane. Fixed point does not lie on the line. Latus Rectum: A chord through focus perpendicular to axis of parabola is called its latus rectum.
Ellipse: It is the set of points in a plane the sum of whose distances from two fixed points in the plane is a constant and is always greater than the distances between the fixed points. Hyperbola: It is the set of all points in a plane, the differences of whose distance from two fixed points in the plane is a constant. Find the equation of hyperbola satisfying given conditions foci 5, 0 and transverse axis is of length 8.
Find equation of an ellipse having vertices 0, 5 and foci 0, 4. Chapter 11 - Work and Energy. Chapter 12 - Sound. Chapter 13 - Why do We Fall ill. Chapter 14 - Natural Resources.

There are two laws of chemical combination- the law of conservation of mass, and the law of constant proportion.
Both these Ncert Solutions For Class 10th Hindi 3rd Language Files laws are discussed in detail in chapter 3, science class 9. There is one important question related to the chemical reaction. Is there any change in the total mass of the system when a chemical reaction takes place? According to the law of conservation of mass, mass can neither be created nor be destroyed.
The same logic stands true for chemical reactions as well. Several experiments carried out by Lavoisier standardized this law.
The law of chemical combination is based on another law- the law of constant proportion. This law was also the result of experiments conducted by Lavoisier and Joseph L. According to the law of constant proportion, any compound is made by mixing two or more elements in a constant proportion, and this proportion does not change irrespective of the source of the compounds.
For example, in water, the ratio of the mass of Hydrogen to the mass of Oxygen is The ratio of the mass is the same for water from different sources. This law is also known as the law of definite proportion. The law of constant proportion is explained thoroughly in Class 9 Science Chapter 3. The issue that the scientist faced with the law of constant proportion is to provide a possible explanation for this.
Eminent scientist John Dalton tried to provide an explanation and introduced the concept of atoms. An atom is the smallest unit of matter. They are so small that thousands of them are stacked in your hair. The atom of one element is different from that of the other elements. Therefore, each of these atoms is depicted by different symbols. Dalton used different combinations Ncert Solutions For Class 10th Geography Chapter 4 Doc of straight lines and circles for denoting various atoms. However, the modern-day symbols consider the first or the first two letters of the element's name to denote an atom of the element.
For example, Hydrogen is denoted by H and Oxygen by O. In some cases, and the Latin names are also considered. For example, the Latin name of Potassium is Kalium, and it is denoted by K. A list of names of elements is shown in Atom and Molecules Class 9.
Every atom has a definite mass, called the atomic mass unit. The atomic mass is the characteristic of the atom. The concept of atomic mass supports the law of constant proportion and the law of conservation of mass.
However, atoms cannot exist freely in nature. It interacts with the same or different atoms to form molecules. They can also form ions. These ions or molecules aggregate to form elements of compounds that we can see. These concepts are covered in Ch 3 Science Class 9. A group of two or more atoms is joined together to form a molecule.
A molecule can exist freely in nature. For example, Hydrogen, Oxygen, Calcium molecules can exist freely in nature.
