Class 10th SIMILAR TRIANGLES Assignments

Triangles: A plane figure bounded by three lines in a plane is called a triangle.

Similar Triangles: Two triangles are said to be similar if

(i)Their corresponding angles are equal and

(ii) Their corresponding sides are proportional.

All congruent triangles are similar but the similar triangles need not be congruent.
Two polygons of the same numbers of sides are similar, if:

(i)Their corresponding angles are equal and

(ii) Their corresponding sides are in the same ratio.

Graph: Graph is one of the most appealing and convincing ways of presenting the data, because graphs are good visual aids and make unwieldy data easily intelligible. There are various methods of graphical representation.

Kinematics

(Assignment for Practice)

Kinematics is a branch of classical mechanics that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the mass of each or the forces that caused the motion. Kinematics, as a field of study, is often referred to as the "geometry of motion" and is occasionally seen as a branch of mathematics. A kinematics problem begins by describing the geometry of the system and declaring the initial conditions of any known values of position, velocity and/or acceleration of points within the system. Then, using arguments from geometry, the position, velocity and acceleration of any unknown parts of the system can be determined. The study of how forces act on masses falls within kinetics.

Class 12 th Physics Current Electricity Assignment

Electric Current

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma).

The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. Electric current is measured using a device called an ammeter.

Electric currents cause Joule heating, which creates light in incandescent light bulbs. They also create magnetic fields, which are used in motors, inductors and generators.
