All questions of Transport System for Class 6 Exam

Explanation:

The correct answer is option 'C' - New Jalpaiguri.

Explanation in detail:

In India, railways use different gauges for different tracks. The three main gauges used in the Indian railway system are broad gauge, meter gauge, and narrow gauge.

Broad gauge:
- Broad gauge is the most commonly used gauge in India.
- The distance between the two rails in broad gauge is 1.676 meters (5 feet 6 inches).
- Most of the major railway lines in India are broad gauge.

Meter gauge:
- Meter gauge has a distance of 1 meter (3 feet 3 3/8 inches) between the two rails.
- Meter gauge was widely used in India before the introduction of broad gauge.
- Some of the railway lines in India still use meter gauge, but they are gradually being converted to broad gauge.

Narrow gauge:
- Narrow gauge has a distance of less than 1 meter (3 feet 3 3/8 inches) between the two rails.
- Narrow gauge tracks are used for specific purposes, such as hill railways and heritage lines.

Answer:

Among the given options, New Jalpaiguri (option 'C') is the only station that has all three gauges - broad gauge, meter gauge, and narrow gauge.
- New Jalpaiguri is located in West Bengal, India.
- It serves as an important junction for trains traveling to the northeastern states of India.
- The station has broad gauge lines that connect it to major cities across the country.
- Additionally, it has meter gauge lines that connect it to nearby areas.
- Lastly, there is a narrow gauge line called the Darjeeling Himalayan Railway (DHR) that originates from New Jalpaiguri. The DHR is a UNESCO World Heritage Site and is famous for its scenic beauty.

Therefore, New Jalpaiguri is the correct answer as it is the only station among the given options that has all three gauges - broad, meter, and narrow.

Road density refers to the length of roads per unit area of land. In this case, we are looking at the road density in India in 2008 per 100 sq. km. land area.

To calculate the road density, we need to know the total length of roads and the land area. However, this information is not provided in the question. Therefore, we have to rely on our knowledge of the topic and make an educated guess based on the options given.

Let's analyze each option and see which one is the most likely answer:

a) 110: This option suggests that there were 110 km of roads per 100 sq. km of land area in India in 2008. While this is a possibility, it seems a bit low considering the size and population of India. India is a large country with a dense population, so it is reasonable to expect a higher road density.

b) 125: This option suggests that there were 125 km of roads per 100 sq. km of land area in India in 2008. This seems like a more reasonable estimate. It implies that there were more roads compared to option a), but not excessively high.

c) 100: This option suggests that there were 100 km of roads per 100 sq. km of land area in India in 2008. This seems unlikely as it implies a lower road density than option a). As mentioned earlier, considering the size and population of India, a higher road density would be expected.

d) 150: This option suggests that there were 150 km of roads per 100 sq. km of land area in India in 2008. While it is possible that India had a high road density, this option seems a bit too high compared to the other options. It would imply an exceptionally high amount of roads per unit area.

Based on the analysis, option b) 125 km of roads per 100 sq. km of land area in India in 2008 seems like the most reasonable answer. However, it is important to note that without specific data, this is just an educated guess.

Responsibility for National Highways
National Highways are crucial for connecting different regions of a country and facilitating trade, travel, and transportation. In India, the responsibility for the construction and maintenance of these highways lies primarily with the Central Government.
Key Responsibilities of the Central Government:
- Policy Formulation: The Central Government develops the policies regarding the planning, construction, and maintenance of National Highways.
- Funding: It allocates funds from the national budget for the building and upkeep of these highways, ensuring that they meet safety and quality standards.
- Implementation: The Central Government oversees the execution of highway projects through various agencies, such as the National Highways Authority of India (NHAI).
- Standardization: It sets the technical and construction standards to be followed, ensuring consistency in quality across the network of National Highways.
Collaboration with State Governments:
- While the Central Government holds primary responsibility, State Governments also play a role in the development of National Highways, especially in terms of land acquisition and local coordination.
- State Governments may assist in maintenance and monitoring activities, but the ultimate accountability rests with the Central Government.
In summary, the construction and maintenance of National Highways is primarily the responsibility of the Central Government, which ensures that these vital routes are developed and maintained efficiently for the benefit of the entire country.

**Commercial Jet Planes**

Commercial jet planes are a type of aircraft that are used for passenger travel. They are designed to be fast and efficient, allowing people to travel long distances in a relatively short amount of time. One of the key factors that determine the speed of a commercial jet plane is its cruising speed.

**Cruising Speed**

The cruising speed of a commercial jet plane refers to the speed at which it typically flies during a long-distance journey. This speed is usually maintained during the majority of the flight and is chosen to optimize fuel efficiency and passenger comfort.

The cruising speed of a commercial jet plane is typically around 500 miles per hour. This means that the plane can cover a distance of 500 miles in one hour of flight.

**Factors Affecting Speed**

There are several factors that can affect the speed of a commercial jet plane. These include:

1. **Aircraft Type**: Different types of commercial jet planes have different cruising speeds. For example, larger planes like the Boeing 747 tend to have higher cruising speeds than smaller planes like the Airbus A320.

2. **Altitude**: Commercial jet planes fly at high altitudes, usually between 30,000 and 40,000 feet. The air is thinner at higher altitudes, which reduces drag and allows the plane to fly faster.

3. **Weather Conditions**: Strong headwinds can slow down a plane's speed, while tailwinds can increase it. Pilots take weather conditions into account when planning their flight paths to ensure optimal speed and safety.

4. **Payload**: The weight of the plane, including passengers, cargo, and fuel, can affect its speed. Heavier planes may fly slightly slower due to increased drag.

**Conclusion**

In conclusion, commercial jet planes typically fly at a cruising speed of around 500 miles per hour. This speed allows for efficient and comfortable long-distance travel. However, it's important to note that the actual speed of a commercial jet plane can vary depending on various factors such as aircraft type, altitude, weather conditions, and payload.
