Work can be represented by Wd (Work done) or Ew (Energy, work). Since it is a form of energy, it is measured in joules
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.

#SPJ1
Since velocity is vector quantity, it'll depend on both direction as well as magnitude hence options C and D are rejected.
Speed = distance/time
Therefore, unit of velocity is m/s.
1. Statement A is true.
When GTP is hydrolysed, the free energy of hydrolyses is used to power or drive reactions that are favourable energetically.
2. Statement B it true.
ATP is a complex chemical that gives energy for the activities in many living cells. During hydrolyses, chemical energy stored in the energy-rich phosphoanhydride is released. Hence its a common source of chemical energy in cells.
3. Statement C is false.
The hydrolyses of ATP to ADP in the presence of phosphate, releases one mole of ATP which is estimated to be -57Kj/mol not 14Kj/mol. Below is the equation;
ATP + H20 -----> ADP + Pi + Free energy.
4. Statement D is false.
GTP stands for guanosine triphosphate.
ATP stands for adenosine triphosphate
ADP stands for adenosine diphosphate.
With an average surface temperature of about 737 K, Venus is the hottest planet.
While Mercury is closest to the sun, it has gaseous molecules that protect it. Venus is the second closest planet to the sun, and is the hottest planet.
