The question asks to identify a major challenge in the development of inland waterways in India. We need to evaluate each option to determine which one represents a significant hurdle.
B) Lack of adequate terminal facilities — This is a significant challenge. For inland waterways to be effective, there must be proper infrastructure at the loading and unloading points, including modern terminals, cargo handling equipment, storage facilities, and good road/rail connectivity. Many Indian waterways lack such facilities, which hampers efficient cargo movement and increases logistics costs.
This problem involves calculating the combined rate of filling and emptying pipes. We will determine the individual rates of the pipes and then find the net rate when both are open. Since the emptying pipe is faster, the cistern will be emptied. We will then calculate the time required to empty the full cistern at this net rate.
Correct Option: D) 40 hours
The question asks to identify the author of the book 'I am a Soldier's wife'. This requires knowledge of contemporary authors and their works, specifically those related to military themes or personal narratives.
Correct Option: D) Geetika Lidder wrote the book 'I am a Soldier's wife'. This book is a memoir reflecting her experiences and emotions as the wife of a military officer, especially after the tragic demise of her husband, Brigadier L.S. Lidder.
The question asks to identify the state with the highest Multidimensional Poverty Index (MPI) according to the National Multidimensional Poverty Index 2023 report. This requires knowledge of the findings of the said report.
B) Bihar had the highest multidimensional poverty index according to the National Multidimensional Poverty Index 2023 report. The report indicated that 33.76% of Bihar's population was multidimensionally poor, making it the state with the highest MPI among all Indian states.
Firoz ranked 38th from the top and 28th from the bottom in his class. How many students are there in his class?
To find the total number of students in the class, we can use the formula for ranking problems. When a person's rank from the top and from the bottom is known, the total number of people can be calculated by adding the two ranks and subtracting 1 (because the person themselves is counted twice).
Correct Option: A) 65
The question asks about the original jurisdiction of the Supreme Court of India. This refers to cases that can be directly filed in the Supreme Court, without first going through lower courts. Understanding the specific types of disputes covered under this jurisdiction is key.
Correct Option: A) The Centre and one or more states. Article 131 of the Indian Constitution grants the Supreme Court exclusive original jurisdiction in any dispute (a) between the Government of India and one or more States; or (b) between the Government of India and any State or States on one side and one or more other States on the other; or (c) between two or more States.
The problem involves calculating the total distance covered by a motorist moving at different speeds for different durations. We need to use the formula \(\text{Distance} = \text{Speed} \times \text{Time}\) and ensure all units are consistent (e.g., km and hours). We will sum the distances covered in each segment of the journey to find the total distance and then solve for the unknown speed 'x'.
Convert time to hours: The total time is 50 minutes. Since speed is given in km/hr, we convert minutes to hours.
\[ \text{Total Time} = 50 \text{ minutes} = \frac{50}{60} \text{ hours} = \frac{5}{6} \text{ hours} \]Calculate distance for each segment:
First segment:
Speed = \(x\) km/hr
Time = 13 minutes = \(\frac{13}{60}\) hours
Distance \[(D_1) = x \times \frac{13}{60} = \frac{13x}{60}\] km
Second segment:
Speed = \(2x\) km/hr
Time = 25 minutes = \(\frac{25}{60}\) hours
Distance \[(D_2) = 2x \times \frac{25}{60} = \frac{50x}{60}\] km
Third segment:
First, find the time for the third segment:
Time for third segment = Total time - (Time for first segment + Time for second segment)
\(= 50 - (13 + 25) = 50 - 38 = 12\) minutes
Convert to hours: \(12 \text{ minutes} = \frac{12}{60}\) hours
Speed = \(x\) km/hr
Distance \[(D_3) = x \times \frac{12}{60} = \frac{12x}{60}\] km
Sum the distances to find the total distance:
The total distance covered is given as 30 km.
\[ D_1 + D_2 + D_3 = 30 \]\[ \frac{13x}{60} + \frac{50x}{60} + \frac{12x}{60} = 30 \]Solve for x:
\[ \frac{13x + 50x + 12x}{60} = 30 \]\[ \frac{75x}{60} = 30 \]\[ 75x = 30 \times 60 \]\[ 75x = 1800 \]\[ x = \frac{1800}{75} \]\[ x = 24 \]D) 24
The value of x is 24 km/hr, which matches the calculation.
This question asks to identify the characteristic of the crest of a wave. Understanding the basic terminology related to wave properties is crucial for answering this question.
C) maximum point — The crest of a wave is defined as the point where the displacement or disturbance from the equilibrium position is at its maximum positive value. For example, in a water wave, it's the highest point of the water surface.
The question asks about the behavior of MS PowerPoint when a new blank presentation is initiated while another presentation is already open. Understanding how modern applications handle multiple document instances is key here.
B) A new MS PowerPoint window opens with the blank presentation. This is the standard behavior for MS PowerPoint (and many other Microsoft Office applications like Word and Excel) when you create a new document while another is already open. Each presentation gets its own top-level window, making it easier to manage and compare multiple files.
