The normal demand curve slopes downwards from left to right, thus showing an inverse relationship between price and the quantity demanded. The exceptional demand curve, on the other hand, is one which slopes down from right to left or in other words, which goes up from left to right.

Hence option D is correct.

According to the giving coding language

Therefore,

SYSTEM = 19251920513

Lysosomes are basically a class of waste disposal system of the cell that helps to maintain the cleanness of the cell by digesting any strange material as well as useless cell organelles.

Ptyalin is an enzyme in the saliva that converts starch into dextrin and maltose. Pepsin is an enzyme that splits proteins into proteoses and peptones. Renin is a proteolytic enzyme secreted by the kidneys that convert angiotensin. Oxytocin is a polypeptide hormone, produced by the posterior lobe of the pituitary gland that stimulates contraction of the smooth muscle of the uterus.

"Urban living is more anonymous living. It often releases the individual from community restraints more common in tradition-oriented societies. "- answers the question.

Wide berth is to maintain a good distance from someone or something. Originally referred to ships. Example: Once I learned that there was a lice outbreak, I gave all of my students a wide berth for the rest of the day.

7 days work of A + B = 5 x 7 = 35
Remaining = 60 - 35 = 25 Time taken by C = 60/25 x 60 = 24

cotθ = 1/tan θ = Base / P Erpendicular = 20/15
Calculate the hypotenuse by using Pythagoras theorem
H² = P² + B²
H =  = √625 = 25
It means,
secθ = 1/cosθ = Hypotenuse / Base = 25/20
sinθ = Perpendicular / hupotenuse = 15/25
sin θ + secθ = 15/25 + 25/20 = 37/20

For the growth of plants, the useful soil moisture is Capillary water.

The liquid and plastic limits exist in Clay soils.

Rabi crops are grown in Rabi season starting from 1^st October and ends on 31^st March. Wheat, barley, gram potatoes etc. are Rabi crops.

A streamline is a line on which tangent drawn at any point gives the direction of flow.

The basic principal of foundation design for large generator is guided, primarily by frequency i.e. no resonances occur and hence the neutral frequency of foundation system should not coincide with the operating frequency of the machine.

When the section is over-reinforcement, concrete reaches its maximum permissible value prior to steel. In over reinforced section, NA depth is large hence, strain across the section remains low. Consequently, the curvature, deflection and crack width also remains low.

In this case the maximum deflection will occur at the centre of the beam where x = L / 2

The BOD value is most commonly expressed in milligrams of oxygen consumed per litre of sample during 5 days of incubation at 20°C and is often used as a surrogate of the degree of organic pollution of water.

The anchorage value of standard bend shall be considered as 4 times the diameter of the bar for each 45° bend subject to a maximum value of 16 times the diameter of the bar. The anchorage value of standard U-type hook shall be 16 times the diameter of the bar.

Modular ratio, m = σcbc
where σcbc is the permissible compressive stress.
For M 20, m 380/3x7 = 13.33

Coefficient of compressibility:

The Pascal law states that the liquid at rest applies pressure at a point is the same in all directions. This means that the pressure is there in spite of the direction. And it is present in the same direction and is having the same magnitude. Explanation: The liquid must be incompressible.

The friction loss In a uniform, straight sections of pipe, known as "major loss", is caused by the effects of viscosity, the movement of fluid molecules against each other or against the (possibly rough) wall of the pipe. Here, it is greatly affected by whether the flow is laminar (Re < 2000) or turbulent (Re > 4000):

• In laminar flow, losses are proportional to fluid velocity, V; that velocity varies smoothly between the bulk of the fluid and the pipe surface, where it is zero. The roughness of the pipe surface influences neither the fluid flow nor the friction loss.
• In turbulent flow, losses are proportional to the square of the fluid velocity, V2; here, a layer of chaotic eddies and vortices near the pipe surface, called the viscous sub-layer, forms the transition to the bulk flow. In this domain, the effects of the roughness of the pipe surface must be considered. It is useful to characterize that roughness as the ratio of the roughness height ε to the pipe diameter D, the "relative roughness". Three sub-domains pertain to turbulent flow:
• In the smooth pipe domain, friction loss is relatively insensitive to roughness.
• In the rough pipe domain, friction loss is dominated by the relative roughness and is insensitive to Reynolds number.
• In the transition domain, friction loss is sensitive to both.
• For Reynolds numbers 2000 < Re < 4000, the flow is unstable, varying with time as vortices within the flow form and vanish randomly. This domain of flow is not well modeled, nor are the details well understood.

Water content is defined as the ratio of the mass of water to the mass of solids.

Percentage of water (% water)=Water content (w) x 100 = 25%

Basic capacity: The basic capacity is the maximum numbers of passenger cars that can pass a given point on a lane or a roadway during one hour under the most ideal roadway and traffic conditions that can possibly be attained.

Possible capacity: It is the maximum number of vehicles that can pass a given point on a lane or roadway during one hour under the prevailing roadway and traffic conditions.

Practical Capacity: It is the maximum number of vehicles that can pass a given point on a lane or roadway during one hour with creating unreasonable delay under the prevailing roadway and traffic conditions.

Design capacity: it is the practical capacity or a smaller value determined for use in designing the highway to accommodate the design hourly volume.

Theoretical Capacity: It is the number of vehicles passing any point in one hour per lane.

For a 50 kg cement bag, water required is 22.5 liters for complete hydration of cement.

Shuttering is measured in terms of area. But generally, square meter and square foot of the contact area with concrete is taken as the unit of measurement.

The dimensions of a shuttering should be measure correct to the centimeter or inches whichever the case may be.

In concrete mix,

The weight of ingredients of concrete mix is taken in kilogram.

Water and aggregates are measured in litres.

The finished concrete is measured in cubic meter.

And water cement ratio is unit less.
Hence option D is correct.

These are prepared by mixing pulverised soil and Portland cement in a specific amount. Water is added and it is compacted to high density. These reduce cement consumption.
