Distillation
Explanation:
The name of the process used to refine oil into different products is called distillation. A refinery has huge distillation columns where is separated into its different fractions.
- Distillation is a separation technique in which a mixture such as crude oil is separated into its fractions.
- The components of the mixture must have an appreciable boiling point difference.
- After distillation, oil is separated into difference components such as heavy oil, natural gas, kerosene, gasoline e.t.c.
- The liquid with the least boiling point rises up in the column first and is collected.

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.

Answer:
Conductors.
Explanation:
Conductors allow the flow of electrons i. e. the current and where some of the electrons energy gets converted into heat while some electrons energy converted into light. Conductors are the materials which has the ability to allow heat and electricity to flow through them. Metals such as gold, copper, Silver, Aluminum, Mercury, Steel, Iron and salty water etc are good conductors of heat and electricity.

Time Required to travel trough d is mathematically given as



Answer:
e)
Explanation:
In an RC series circuit, at any time, the sum of the voltages through the resistor and the capacitor must be constant and equal to the voltage of the DC voltage source, in order to be compliant with KVL.
At= 0, as the voltage through the capacitor can't change instantaneously, all the voltage appears through the resistor, which means that a current flows, that begins to charge the capacitor, up to a point that the voltage through the capacitor is exactly equal to the DC voltage, so no current flows in the circuit anymore, and the charge in the capacitor reaches to its maximum value.
