What is Super Passage?
When the canal is in full cutting and there is SUFFICIENT HEAD way for the canal water a Super Passage may be proposed. That is if the Full supply level (F.S.L) of canal is below a depth of free board required for canal from bed level of drain CROSSING, at this point a super passage may be constructed to let the discharge of drain without causing any damage to the canal.
What is AQUEDUCT?
Aqueduct is a structure that may be proposed on canal that is running in full embankment and there is sufficient way to pass the discharge of drain. That is if the Maximum Flood Level (M.F.L) of drain is below a depth of free board required in drain from Bed Level Canal, at this point an aqueduct may be proposed to let the discharge of drain below canal without causing any damage to the canal.
What is Under Tunnel (Type-2 Aqueduct)?
When the canal is running in partial or full embankment and there is no sufficient head way to pass the discharge of drain below the canal then an Under Tunnel may be proposed. That is if the (MFL +Freeboard) of drain is above the bed level of canal, then a barrel will be provided below the canal bed level by depressing the bed level of the drain.
What is Canal Syphon?
When the canal runs partially in cutting, the canal syphon may be adopted. A barrel will be provided below the bed level of drain to pass the discharge of canal by depressing canal Full supply level (F.S.L) before the drain crossing and again lift it back after crossing the drain. Sufficient head may be provided to force the water from up stream of canal to down stream of canal. This is often provided for drain crossing that have huge discharge and an Under Tunnel may not be economic.

The normal function of a gallery is to provide access for inspection PURPOSES, to monitor the behaviour of the dam, and to carry out remedial work if REQUIRED. It must therefore be of sufficient height to permit easy movement of personnel and minor equipment, commonly 2.13m but varied to suit CONSTRUCTION methods. The width is usually 1.5m but should be related to the function of the gallery. Wide opennings induce quite high local stresses with consequent cracking of the concrete. Spiral staircases can link other galleries, ventillation and pipes in quite a small shaft.

Circular shafts are the most desirable, with a removable floor covering DRAINAGE, but it is harder and more expensive to FORM. Rectangular galleries require greater amounts of reinforcement. Galleries also should be well lit and ventillated.

Reservoir Zones and Operation. Reservoir STORAGE is divided into four zones, or pools. These include, from TOP to bottom, the flood-control zone, conservation zone, buffer zone and inactive zone. The conservation and buffer pools, together, constitute the reservoir's ACTIVE storage.

The arrow simply denotes that CONVENTIONAL current FLOWS from emitter to BASE (i.e from p-type (emitter) to n-type(base) in pnptransistor. It INDICATES the direction of conventional current inside the device. So,in the casof NPN, it is flowing out. In the case of pnp it is flowing in.

ANSWER:-
Start from the work-energy theorem, then add in Newton's second LAW of motion.

ΔK = W = FΔs = maΔs

Take the the appropriate equation from kinematics and rearrange it a bit.

v2 = v02 + 2aΔs  aΔs = v2 − v022

Combine the two expressions.

ΔK = m ⎛
⎝v2 − v02⎞
⎠2

And now something a bit unusual. Expand.

ΔK = 1 mv2 − 1 mv0222

If kinetic energy is the energy of motion then, naturally, the kinetic energy of an object at rest should be zero. Therefore, we don't need the second term and an object's kinetic energy is just…

K = ½mv2

Derivation using CALCULUS (but now we don't need to assume anything about the acceleration). Again, start from the work-energy theorem and add in Newton's second law of motion (the calculus version).

ΔK = W  ΔK = ⌠
⌡F(r) · dr  ΔK = ⌠
⌡ma · dr  ΔK = m⌠
⌡dv · drdt

Rearrange the differential terms to get the integral and the function into agreement.

ΔK = m⌠
⌡dv · drdtΔK = m⌠
⌡dr · dv dtΔK = m⌠
⌡ v · dv  

The integral of which is quite simple to evaluate over the limits initial speed (v) to final speed (V0).

ΔK = 1 mv2 − 1 mv0222

Naturally, the kinetic energy of an object at rest should be zero. Thus an object's kinetic energy is DEFINED mathematically by the following equation…

K = ½mv2.

# Answer- 2.5 s

# Explanation-

# Given-

Initial period Ti=2s

Speed of OBSERVER v=0.6c

# Solution-

Consider Tf be period MEASURED by observer

Tf=γTi

By Einsteins THEORY of relativity

γ=1/√[1-(v/c)^2]

γ=1/√[1-(0.6)^2]

γ=1/√(1-0.36)

γ=1/√0.64

γ=1/0.8

γ=1.25

Now,

Tf=γTi

Tf=1.25×2

Tf=2.5s

Period of pendulum measured by observer is 2.5s.

Neutrino means :

A neutrino is a fermion that interacts only via the weak subatomic FORCE and GRAVITY. The MASS of the neutrino is much smaller than that of the other KNOWN elementary PARTICLES.

Airport markings and signs, both in the United States and internationally, are STANDARDIZED by the International Civil Aviation Organization (ICAO) to ENHANCE safety and improve efficiencyMarkings break down as:Runway MarkingsTaxiway MarkingsHolding Position MarkingsOther MarkingsMandatory Instruction SignsDirection SignsDestination SignsLocation Signs
Marking Colors:
Markings on runways are whiteMarkings defining the landing area on a heliport are also white except for hospital heliports which use a red "H" on a white crossMarkings for taxiways, areas not intended for use by aircraft (closed and hazardous areas), and holding positions (EVEN if they are on a runway) are yellow.

Power = WORK by TIME
work =Force × displacement

In the MAGNETIC field ,magnetic force and displacement of charge are perpendicular, so the work done is ZERO.If work is zero ,power is also zero

The same,10m/s
velocity =DISPLACEMENT ÷time
it is INDEPENDENT of MASS

It can PROVIDE MUCH ENERGY which is GREATER than THRESHOLD energy

According to question

Kinetic ENERGY with which the body is thrown

KE = 10 j

While going up the energy Changes to potential energy

Thus

PE =  10 J

We know 

PE = m * g * H

10  =  m * 10 * 5

m = 10 / 50

m  =  0.2 Kg

Thus  MASS of body is o.2 Kg

Coning of wheels is a METHOD of beveling the wheels to avoid depreciation to the wheels and rims. Normally the wheels are conned by a CONE of semi-angle. It is based on the theorem of coning

PURPOSE ⬇️⬇️⬇️⬇️

To keep the TRAIN in its central position of the rails, coning does not ALLOW any sidewise movement on a straight TRACK. to allow the wheelsto move different distances on a curved track and thereby reduce wear and tear.

The pressure exerted by a STATIC fluid depends only UPON the DEPTH of the fluid, the density of the fluid, and the acceleration of gravity. The most remarkable thing about this EXPRESSION is what it does not include. The fluid pressure at a given depth does not depend upon the total mass or total VOLUME of the liquid.

Natural and artificial harbor:

• A natural harbor is a place with deep water that is sheltered from the most COMMON strong winds and GIANT WAVES.  

• A natural harbor is a geographic feature which provides space and some other key benefits to watercraft.

•  An artificial harbor can have intentionally constructed breakwaters, sea WALLS, or they can be constructed by searching, which requires upkeep by further periodic dredging.

Universal law of gravitation has a lot of importance
-------------------------------------------------
Newton's law of universal gravitation states that a particle attracts every other particle in the universe with a FORCE that is directly proportional to the PRODUCT of their MASSES and inversely proportional to the square of the distance between their centers
----------------------
1)with the help of this we can understand the force experience by VARIOUS planets , stars with each other

2)we can understand how and why the planets revolve around the sun and how satellite revolved around the planets

3)it explains how the planets are held by the sun and why don't they fall on sun

4)it can also explain how is tided formed of earth , it can be due to the GRAVITATIONAL forces of sun moon etc as there will be low tides on no moon day and high tides on new moon day

5)it can also explain how far the gravitational force exists between the bodies in the universe 

6)gravity in different planets is different and there is a universal gravitational constant whose values is 6.674 x 

gravitational force is a long range force but it is the weakest force

if the cage is completely CLOSED and has no HOLES then  For the bird to stay in the air, the wings must PUSH down on the air under them. The air exerts an equal force on the floor of the cage. The net force down on the scale will remain CONSTANT.  

IF the cage is not air tight, the air will move down and horizontal. The force down will be less than the WEIGHT of the bird

ENERGY can be calculated using the mass-energy formula: .
