number field

In this chapter, we have seen how arranging numbers in orderly rows and columns under the guise of Matrices and Determinants, has helped to solve linear equations or find the area of a triangle. There are in fact other much wider applications in Science and Engineering and other ..

Conclusion - We have seen the application of matrices and determinants in solving system of linear equation with three unknown variables. Matrices and determinants are also widely used in solving large system of linear equation. Some of these methods are Gauss-elimination method, Gauss-Jordan metho..

Determine if the set of natural numbers and the operation of multiplication form a field. => Yes or No..

Students from Grade 4 to Grade 8 were taken on a field trip. The number of students from each grade were 32, 36, 24, 28 and 30 respectively. Which line graph represents the students who made it to the field trip from each grade? => Graph 2 or Graph 3 or Graph 1 or Grap..

There are 27 sheep and 23 dogs in a field. Find the value of ' y ', if y represents the total number of animals in the field. => y = - 50 or y = 23 or y = 50 or y = 27..

The compass needle always lies along the direction of the field. The figure below shows the lines or pattern of the field, when the compass needle is placed at several places. These lines do not really, tell us the effect that magnet has on the other. These field lines..

A solenoid is a long coil (shaped like a cylinder) containing a large number of close turns of insulated copper wire. The figure above shows a solenoid SN whose ends are connected to a battery B through a switch X. When a current is passed through a solenoid, it produces a magnetic ..

Toroid is a hollow circular ring (like a medu vadai) on which a large number of turns of a wire are wound. The above figure represents a toroid wound with a wire carrying a current I. Consider path 1, by symmetry , if there is any field at all in this region, it will be tangent ..

A solenoid is a long coil (shaped like a cylinder) containing a large number of close turns of insulated copper wir..

Let us now calculate the electric flux passing through a surface when the applied field is not uniform. The surface is usually divided into a large number of small area dA such that the electric field remains constant over that surface as shown in the figure. The ..
