What is the input of energy for a device that provides 50 units of useful energy and has an efficiency of 0.55?
ki77a [65]

If that's the case, then  

                          50 units = 0.55 x the input energy

Divide each side by  0.55 :        

                   50 units/0.55  =  the input energy = 

                              <span> 90 and 10/11 units</span>

Using a schematic diagram, explain the steps of the laser technique.
nignag [31]

The steps of the use of the laser technique is explained below:

  • A laser beam is emitted from the diode in the unit and spread into a laser plane (1).
  • The laser plane, appearing as a line on the sphere (2), is reflected and collected by dual CCD arrays (1).
  • The resulting 2D profile is digitized and as the unit travels along the x-axis of the object, multiple profiles are collected yielding a 3D coordinate point cloud of the surface (3).

<h3>What is a Laser Technique?</h3>

This refers to the type of surgery that makes use of special light beams in order to cut open the human body in a surgical procedure.

Hence, we can see that the laser technique is considered safer than conventional surgical methods.

Laser techniques include:

  • laser vaporization,
  • laser resection-enucleation,  
  • coagulation.
