Distance
Question : A train starts from place S at 10: 00 a.m. and arrives at another place T at 2: 30 p.m. on the same day. If the speed of the train is 40 m/s, then what will be the distance covered by the train?
Option 1: 706 km
Option 2: 648 km
Option 3: 726 km
Option 4: 616 km
Correct Answer: 648 km
Solution : Start time = 10:00 a.m. End time = 2:30 p.m. Speed = 40 m/s ⇒ Time = 2:30 p.m. – 10:00 a.m. = 4.5 hours = 16200 seconds ⇒ Distance = Speed × Time = 40 × 16200 = 648,000 meters = 648 km Hence, the distance covered by the train is 648 km. Hence, the correct answer is 648 km.
Question : Select the most appropriate option to fill in the blank. The ______ for this distance will be ninety cents.
Option 1: flair
Option 2: flower
Option 3: fair
Option 4: fare
Correct Answer: fare
Solution : The correct choice is the fourth option.
Explanation: In this context, "fare" refers to the price or cost of travel, specifically for the mentioned distance. It's commonly used in transportation contexts when referring to the fee one pays for a journey.
The meanings of the other options are as follows:
Therefore, the complete sentence would be: The fare for this distance will be ninety cents.
Question : Comprehension:
Read the following passage and answer the questions.
On a cold, wintry Christmas day in 1998, the ice and snow were beating down upon the windows of the vehicles as we travelled to an obscure orphanage in Bosnia and Herzegovina. We battled unstable hills blanketed with two feet of snow. The narrow road forced us to drive perilously close to the edge. This would be my first Christmas away from home and family. I could imagine my wife and my two little daughters opening their gifts on Christmas day. Today, I was going to learn for the first time how it would be to spend Christmas day with other children.
Enemy activity had devastated the villages. I had heard stories and seen pictures of this particular village where we were headed. What I did not know was that it would be a camp full of destitute families and children. As we entered the village, the children lined the roads on both sides and cheered. They ran to us in excitement as we climbed out of our vehicles. Within moments, I saw my soldiers passing out sweets and chocolates and talking with the children. The adults, who were not sure if we could be trusted, kept their distance. But soon, they too were won over by my men. The soldiers unloaded 87 boxes of toys, clothes, shoes, school supplies, and candy. We were soon surrounded by the people of the village, who shook our hands and smiled shyly in thanks for our gifts and our presence.
After the two hour visit, as we rose to leave, the camp leader said to us, "Please come again, even if you have nothing to give. We enjoyed having you here." We had loved every moment we had been there. This year, we truly learned the Christmas spirit of loving and giving!
Question:
Which of these statements is NOT true?
Option 1: The village had been reduced to a camp for the destitute families.
Option 2: The villagers wanted only gifts from the soldiers.
Option 3: Children were excited to meet the soldiers.
Option 4: It was the narrator’s first Christmas away from home.
Correct Answer: The villagers wanted only gifts from the soldiers.
Solution : The correct choice is the second option.
Explanation: The passage does not suggest that the villagers only wanted gifts from the soldiers. While the soldiers did distribute gifts such as toys, clothes, shoes, school supplies, and candy, the deeper appreciation from the villagers extended beyond material items. The camp leader explicitly mentioned, "Please come again, even if you have nothing to give. We enjoyed having you here." This statement implies that the villagers valued the soldiers' presence and the positive interactions, expressing a desire for the soldiers to return, irrespective of material gifts.
Therefore, the correct answer would be: The villagers wanted only gifts from the soldiers.
Question : Two bodies kept at a certain distance feel a great gravitational force F to each other. If the distance between them is double the former distance, the force will be:
Option 1: 2F
Option 2: 1/2 F
Option 3: 4F
Option 4: 1/4 F
Correct Answer: 1/4 F
Solution : The correct option is 1/4 F.
When two bodies are twice as far apart, the gravitational force that attracts them is reduced to one-fourth of its initial amount. This is because the gravitational pull between two bodies is inversely proportional to their squared distances. As a result, as a body's distance doubles, the force of attraction between them drops by a factor of 1/4, or 25%, of its initial value.
Question : Trains A and B are running in the same direction at 40 km/hr and 60 km/hr, respectively. If both the trains start at the same time from the same place, then what will be the distance between them after 1 hour?
Option 1: 10 km
Option 2: 20 km
Option 3: 40 km
Option 4: 0 km
Correct Answer: 20 km
Solution : Relative speed = 60 – 40 = 20 km/hr Time = 1 hour Distance between them after 1 hour = 20 × 1 = 20 km Hence, the correct answer is 20 km.
Question : Which of the following supports the particle nature of photons?
Option 1: Diffraction
Option 2: Polarisation
Option 3: Photoelectric effect
Option 4: Interference
Correct Answer: Photoelectric effect
Solution : The correct answer is the Photoelectric effect.
In the photoelectric effect, when light shines on a material surface, it can eject electrons from that material. The key observation is that the intensity of light doesn't determine whether electrons are emitted but rather the frequency of the light. This phenomenon is best explained by considering light as discrete packets of energy or photons.
Question : Directions: Suyash starts walking from Point A and goes 130 m towards the southeast. Pradeep starts walking from Point B and goes 130 m towards the southwest. After walking these distances, they both meet at Point C. Point D is located in such a way that if points A and B are connected with a straight line, then D would be the midpoint of that line. The distance between Point C and Point D is 120 m. What is the distance between Point A and Point B?
Option 1: 120 m
Option 2: 100 m
Option 3: 80 m
Option 4: 50 m
Correct Answer: 100 m
Solution : According to the instructions given, the diagram is as follows –
Now, we have to calculate the distance between A and B.
Here, A is the starting point of Suyash, B is the starting point of Pradeep and C is the meeting point of both. AC = BC = 130m; CD = 120m Calculate the distance between AD using the Pythagoras Theorem – (AC)2 = (AD)2 + (CD)2 (130)2 = (AD)2 + (120)2 16900 = (AD)2 + 14400 16900 – 14400 = (AD)2 (AD)2 = 2500 AD = 50m Similarly, BD = 50m
Therefore, AB = 100m. Hence, the second option is correct.
