Examples of application in the following topics:

 Linear algebra and its application.

 The controlled use of sound waves has many applications in science.
 The most common use of ultrasound, creating images, has industrial and medical applications.

 The force vectors show direction and point of application and are labeled with their magnitude.
 The engineer who drew this diagram has used the tip of the arrow to indicate the point of application of a force.
 The point of application of a force becomes crucial and has to be indicated on the diagram.
 Some engineers use the tail of the arrow to indicate the point of application.
 In a fully solved problem, a force arrow is capable of indicating the direction, the magnitude the point of application.

 Cyclotrons, magnetrons, and mass spectrometers represent practical technological applications of electromagnetic fields.
 The consequences of such motion can have profoundly practical applications.
 The magnetron has practical applications in radar, heating (as the primary component of a microwave oven), and lighting.
 Discuss application of mass spectrometers, movement of charged particles in a cyclotron, and how microwaves are generated in the cavity magnetron

 Semiconductor detectors have had various applications in recent decades, in particular in gamma and xray spectrometry and as particle detectors.
 Other applications of scintillators include CT scanners and gamma cameras in medical diagnostics, screens in computer monitors, and television sets.

 To understand what factors affect rotation, let us think about what happens when you open an ordinary door by rotating it on its hinges.The magnitude, direction, and point of application of the force are incorporated into the definition of the physical quantity called torque—the rotational equivalent of a force.
 In equation form, the magnitude of torque is defined to be τ=rFsinθ where τ (the Greek letter tau) is the symbol for torque, r is the distance from the pivot point to the point where the force is applied, F is the magnitude of the force, and θ is the angle between the force and the vector directed from the point of application to the pivot point.

 Kirchhoff's junction rule, also known as Kirchhoff's current law (KCL), Kirchoff's first law, Kirchhoff's point rule, and Kirchhoff's nodal rule, is an application of the principle of conservation of electric charge.
 Kirchhoff's junction law is limited in its applicability.

 Mobile phone, also called cellular phone, is the best known example of application wireless communication technology.
 It encompasses various types of fixed, mobile, and portable applications, including twoway radios, cellular telephones, personal digital assistants (PDAs), and wireless networking.
 Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television, and cordless telephones.

 The first is the application of elementary operations to try to put the matrix in rowreduced form; i.e., making zero all the elements below the main diagonal (and normalizing the diagonal elements to 1).

 The phenomenon of turbulent air flow must be accounted for in many applications.
 Turbulent flow is thus desirable in applications where a relatively cool fluid is mixed with a warmer fluid to reduce the temperature of the warmer fluid.
