Explanation
Entomology is the scientific study of insects. It involves the observation, classification, and understanding of various aspects of insects, including their behavior, anatomy, physiology, ecology, and evolution. This field of study helps in identifying and categorizing different insect species, understanding their role in ecosystems, and developing effective pest control strategies. By studying insects, entomologists contribute to our knowledge of biodiversity, agriculture, public health, and conservation efforts.

India is the correct answer because the 2017 T20 Blind cricket world cup was indeed hosted by India.

Explanation
Vijay Singh is a famous golf player who hails from Fiji.

Explanation
FFC stands for Film Finance Corporation. This organization is responsible for providing financial support and funding to the film industry. They assist in the production, distribution, and promotion of films. The Film Finance Corporation plays a crucial role in the development of the film industry by ensuring that filmmakers have access to the necessary funds to bring their projects to life.

Explanation
Faraday is credited with discovering the magnetic field of electric current. Through his experiments, he found that when an electric current flows through a wire, it creates a magnetic field around it. This discovery laid the foundation for the understanding of electromagnetism and the development of various electrical devices and technologies. Faraday's work on electromagnetic induction also led to the development of generators and transformers, revolutionizing the field of electricity.

Explanation
Epoxy resins are commonly used as adhesives because of their strong bonding properties. They have excellent adhesion to a variety of materials, including metals, plastics, and wood. Epoxy adhesives provide high strength and durability, making them suitable for applications that require a long-lasting bond. Additionally, they have good resistance to chemicals, heat, and moisture, further enhancing their effectiveness as adhesives.

Explanation
Service connections to consumer houses are generally provided with galvanized iron pipes because galvanized iron pipes are highly durable and resistant to corrosion. These pipes are coated with a layer of zinc, which acts as a protective barrier against rust and other forms of damage. Additionally, galvanized iron pipes are easy to install, cost-effective, and have a long lifespan, making them a popular choice for service connections.

Explanation
Thiamine is the correct chemical name for Vitamin B. It is also known as Vitamin B1. Thiamine plays a crucial role in the metabolism of carbohydrates, helping convert them into energy. It is essential for the proper functioning of the nervous system and the maintenance of a healthy heart. Thiamine deficiency can lead to various health problems, including beriberi and Wernicke-Korsakoff syndrome. Therefore, thiamine is an important vitamin for overall health and well-being.

Explanation
The minimum grade of concrete is M5. This means that the concrete has a minimum compressive strength of 5 megapascals (MPa) after 28 days of curing. The higher the grade, the stronger the concrete. M5 is the lowest grade of concrete and is typically used for non-structural purposes such as leveling or filling. It is important to use the appropriate grade of concrete for different applications to ensure the desired strength and durability.

Explanation
The escape speed of Earth refers to the minimum velocity required for an object to escape Earth's gravitational pull and move into space. In this case, the correct answer is 11.2km/s, indicating that an object needs to achieve a speed of 11.2 kilometers per second to overcome Earth's gravity and escape into space.

Explanation
The unit of kinematic viscosity is m2/s, which represents the ratio of dynamic viscosity to density. It is a measure of a fluid's resistance to flow under the influence of gravity. The higher the kinematic viscosity, the more resistant the fluid is to flow. This unit is commonly used in fluid mechanics and is important in determining the behavior of fluids in various applications such as lubrication, fluid dynamics, and heat transfer.

Explanation
The number of reactions created in a fixed support is 3. A fixed support is a type of support that prevents both translation and rotation of a structure. It generates three reactions: two vertical reactions (one upward and one downward) and one horizontal reaction. These reactions are necessary to maintain the equilibrium of the structure and ensure its stability.

Explanation
The mix proportion of M20 concrete is given as 1:1.5:3. This means that for every 1 part of cement, we need 1.5 parts of sand and 3 parts of aggregate. This mix proportion is commonly used for construction purposes as it provides a good balance between strength and workability of the concrete. By following this mix proportion, the concrete will have the desired strength and durability for its intended use.

Explanation
The least count of a theodolite refers to the smallest measurement that can be accurately read or recorded using the instrument. In this case, the least count of the theodolite is 20 seconds. This means that the theodolite can measure angles with an accuracy of up to 20 seconds.

Explanation
John Smeaton is considered the father of civil engineering because he was the first person to be recognized as a civil engineer and to apply scientific principles to the field. He is known for his work on the Eddystone Lighthouse, which demonstrated his innovative engineering techniques and laid the foundation for modern civil engineering practices. Smeaton's contributions to the field paved the way for the development and growth of civil engineering as a distinct profession.

Explanation
The correct answer is "vicat,vicat apparatus". The vicat apparatus is a device used to determine the initial and final setting time of cement. It consists of a movable rod with a needle attached to it, which is lowered into a cement paste sample. The initial setting time is the time taken for the needle to penetrate a specific distance into the cement paste, while the final setting time is the time when the needle no longer makes an impression on the cement paste. Therefore, the vicat apparatus is the appropriate apparatus for this purpose.

Explanation
Seasoning is the process of reducing the moisture content of wood to make it more suitable for use as timber. This is done by drying the wood slowly and evenly, either naturally or artificially. Seasoning helps to prevent shrinkage, warping, and cracking of the wood, making it more stable and durable. It also improves the strength and workability of the wood, making it easier to cut, shape, and join. Overall, seasoning is an important step in preparing wood for various construction and woodworking purposes.

Explanation
Principal planes are the planes on which the resultant stress is the normal stress. This means that the stress acting on these planes is purely in the form of normal or perpendicular forces. The normal stress is the stress that acts perpendicular to the surface of an object, causing it to compress or elongate. In the context of principal planes, it implies that the stress on these planes is only in the form of compressive or tensile forces acting perpendicular to the plane, without any shear or tangential components.

Explanation
The bending stress at the neutral axis is zero because it is the location within a beam where the bending moment is zero. At this point, the fibers of the beam experience neither compression nor tension, resulting in no stress. This occurs because the neutral axis is located at the centroid of the beam's cross-section, where the internal forces balance each other out.

Explanation
When a structure is statically indeterminate, it means that the internal forces and reactions within the structure cannot be determined solely by applying the equations of static equilibrium. This occurs when there are more supports or constraints in the structure than the minimum required for stability. The additional supports introduce redundant or extra reactions, making it impossible to determine the exact distribution of forces within the structure using equilibrium equations alone. Therefore, the structure becomes statically indeterminate.
