Solution:-
t = 20 second.
u = 72 km/hr = 72×1000 / 3600
u = 20 m/s
v = 36 km/hr = 36×1000 / 3600
v = 10m/s
a = v - u / t
= 10 - 20 / 20
= -10 / 20
a = - 0. 5 m/s2
v2 = u2 + 2as
S = v2 - u2 / 2a
= (10)2 - (20)2 / (2 ) × (- 0.5)
= 100 - 400 / -1
= -300 / -1
S = 300 m
∴ The length of the tunnel is 300m.
Hello friends my name is Rajakumar Dayashankar Gupta . Here I am started to write blog on name scientechplus . I am started to writing this blog post on science , technology and engineering since 2020 . I completing my ssc , than after I go for stream in science field , than after completing my 12th science than later I realize my self , I am interested in electronics fields , so I start learning in diploma electronics engineering . My journey is quite interesting to choosing right decision of my aim . And I want to explain the concept in simple and precise way . I every time want to learn something new , it means that something new from open minded from our environment . To learn something new from our expectation . It quite special and very interested to hear that , when we imagine or think we go to learn something very uniqueness our eyes fill with glow , that moment is such a very great pleasurable moment we feel isn't it ? . And I want to share the information , facts , knowledge related to all science , technology and engineering in detail , simple and precise way .
1) Optical fiber connectors are used to join optical fiber where a connect /disconnect capability is required.
2) Optical fiber connectors are used in telephone exchange for customer premises wiring and in outside plant applications to connect equipment and fiber-optical cables.
3) Outside plant application may require connectors be located underground or on outdoors walls or utility poles.

1) In general there are two situation in which compensation is required.
2) In 1st case, the system is absolutely unstable & the compensation is required to stabilize, if as well as to achieve a specified performance.
3) In 2nd case the system is stable, but the compensation is required to obtain the desired performance.
4) The system which are type 2 or higher are usually absolutely unstable, for these type of system clearly load compensator increase the margin of stability.
5) In type 0, type 1 system stable operation is always possible, if the gain if sufficiently reduced. In Such cases any of the 3 compensator lead, lag and Lead lag may be used to obtained the desired performance.

1) An optical switch is a device that selectively switches optical signals from one channel to another.
2) In commercial terms it refer to any piece of circuit switching equipment between fibers.
3) The switches are used to switch the traffic stream from primary fiber into another fiber in case the primary fiber fails.

Rectifier is a electronic circuit or a device which is used for converting AC voltage/current to DC voltage/current.
Requirements of rectifiers:- i) Rectifier is able to convert two directional Alternate Current (AC) to unidirectional pulsating Direct Current (DC).
ii) Rectifier removes, the negative part from Alternate Current (AC).
iii) By using Rectifier and step-down transformer we get desired DC voltage.
iv) Rectifier divided into two types:- a) Half wave rectifier
b) Full wave rectifier

GPON or Gigabit passive optical network is a point to multipoint access mechanism.
The main characteristics of GPON is the use of passive splitters, which enable a single feeding fiber from the networks provider's central location to serve multiple users with their homes and small business.
GPON uses the advanced Encryption standard (AES) for security purpose, which was designed to be efficient in both hardware and software and support a block length of 128 bits and key length 128, 192 and 256 bits.
GPON also support all types of Ethernet protocol.
