\(2.613\:\cdot10^5\) Joules ; 5. Adding the same amount of heat to two different objects will produce the same increase in temperature ; 2. Same speed in both ; 2. A
Explanation:
Diagram 1 ( Liquid Nitrogen ) : So as you can see, we want our units in Joules here, and can therefore multiply the mass of gaseous nitrogen and the latent heat of liquid nitrogen, to cancel the units kg, and receive our solution - in terms of Joules. Let's do it.
q ( energy removed ) = mass of nitrogen \(*\) latent heat of liquid nitrogen,
q = 1.3 kg \(*\) 2.01 \(*\) 10⁵ J / kg = \(1.3\:\cdot \:2.01\:\cdot \:\:10^5\) = \(10^5\cdot \:2.613\) = \(100000\cdot \:2.613\) = \(261300\) Joules = \(261.3\) kiloJoules = 2.613 \(*\) 10⁵Joules is the energy that must be removed
Diagram 2 : The same amount of heat does not necessarily mean the same increase in temperature for two different objects. The increase in temperature depends on the specific heat capacity of the substance. Therefore your solution is 5 ) Adding the same amount of heat to two different objects will produce the same increase in temperature.
Diagram 3 : The temperatures in both glasses are the same, and hence the molecules have the same average speed. Therefore your solution is 2 ) Same speed in both.
Diagram 4 : Glass A has more water molecules, and hence has more thermal energy. Your solution is 2 ) A.
What will be the pressure exerted by the object if 5000N of the force is acting on an area of 200 cm square

The average woodpecker smashes its beak against a hard surface more than 10,000 times a day. Any human who jolted their head like this would likely end up with a concussion. This traumatic brain injury is caused by a blow to the skull. So why doesn’t the constant hammering turn woodpeckers’ brains into mush? For years, it was assumed that woodpeckers had some kind of cushioning in their heads to protect their brains during pecking. Many scientists suggested that spongy bone in the birds’ skulls absorbed and lessened the shock of each impact (see Myth Buster: Hard Headed). This idea was repeated in scientific articles, textbooks, and informative plaques at zoos. Even though the concept “is often presented like a clear-cut fact, there haven’t been any real tests to prove it,” says Sam Van Wassenbergh. He’s a biologist who studies biomechanics, or how living things move, at the University of Antwerp in Belgium.SHOCK ABSORBER: Van Wassenbergh uses a spring-loaded hammer to show why a shock-absorbing skull would make a woodpecker less efficient at pecking. When you think about it, says Van Wassenbergh, the shock-absorbing skull idea doesn’t make much sense. Woodpecker drills into the wood in search of insects to eat. When the bird’s head accelerates forward, the movement generates kinetic energy. This energy of motion is transferred to the tree when the bird slams its beak against the trunk. If a woodpecker’s skull had to cushion, it would absorb some of this energy and decrease the force of the peck. Why would a bird that survives by pecking evolve to do it less effectively? Van Wassenbergh and his team decided to see what was really going on. First, the researchers recorded videos of woodpeckers’ heads in motion. To capture this rapid movement, the scientists needed special high-speed cameras. Each peck lasts only a fraction of a second! Van Wassenbergh’s team recorded videos of six woodpeckers from three species and analyzed the footage. The researchers used a computer to track three points on each bird’s head: one on the skull and two on the beak. The scientists hypothesized that if the birds’ skulls had shock absorbers, the footage would show a “squishing” of the space between the skull and beak—like when a spring compresses. But that didn’t happen. Instead, the birds’ heads moved as one stiff unit, like a hammer. Next, the team wanted to demonstrate why this adaptation would be helpful to the birds. Using computer models, the scientists simulated woodpecker skulls with and without shock absorbers. Then the researchers compared the force of the pecks. “The pecking performance was greatly reduced in the skull with a shock absorber,” says Maja Mielke, a biologist who worked on the study. With shock absorbers, says Mielke, “the poor birds would need to pound even harder to reach the same results.” For a woodpecker, having a shock-absorbing skull would simply be a waste of energy. Science World originally published this diagram in our May 10, 2021, issue. It was based on scientists’ beliefs about woodpecker anatomy at the time. Here it is again—updated based on new research. MYTH: The skull is made of spongy bone that cushions and protects the brain from impactBUSTED! The skull is hard enough to protect the bird from injury, but it doesn’t cushion The eyes have a special membrane that protects them from flying splinters and wood dust.MYTH: Neck muscles are strong and stiff enough to absorb the shock of each peck BUSTED! Stiff neck muscles do not absorb shock—in fact, they help increase the force of each peck.MYTH: The tongue wraps completely around the outside of the skull, providing an additional level of cushioning, and can extend to probe for food inside holes made by the birdBUSTED! The tongue does not provide any observable cushioning. The beak is connected to the skull with thick bone that prevents jolts and vibrations. NEW RESEARCH SHOWS: The woodpecker’s brain is small, which helps prevent concussions that might occur in a larger animal. If woodpeckers’ skulls don’t absorb shock, then why doesn’t constant pecking damage the birds’ brains? To answer this question, the researchers calculated how harmful the blows from pecking actually are. It turns out the hits aren’t that dangerous because the birds’ brains are so small. “Small masses can tolerate stronger impact forces without being damaged,” says Mielke.
Answer:
The topic of the story is about how woodpeckers can peck without causing damage to their brains.
"The average woodpecker smashes its beak against a hard surface more than 10,000 times a day."
"This traumatic brain injury is caused by a blow to the skull."
"So why doesn’t the constant hammering turn woodpeckers’ brains into mush?"
The conclusion of the story is that woodpeckers don't get brain damage from pecking because their brains are small, which allows them to handle the force of the pecks.
"Small masses can tolerate stronger impact forces without being damaged,"
"The hits aren’t that dangerous because the birds’ brains are so small."
"To answer this question, the researchers calculated how harmful the blows from pecking actually are."

-the same weight and the same mass.
-a larger weight, but smaller mass.
-a smaller mass and larger weight.
- a smaller weight and the same mass.
Answer:
D) a smaller weight and the same mass is the answer
Explanation:
The rover Spirit is having a smaller weight and the same mass on Mars because of the Strength of Gravity on Mars
The Strength of Gravity depends on the mass of the object as gravity is directly proportional to mass which means more mass more gravity and vice versa

Mahiya and Mrinmoy are in a relay around a square field with each side of length 60m. First, Mahiya runs at a speed of 6 ms−1 for 60m to pass a baton to Mrinmoy. Then Mrinmoy runs 120m at 4ms−1 while Mahiya runs through the field to reach the other corner. Then Mrinmoy passes the baton. But Mahiya is now tired since she has been constantly running. So, she only runs at 3ms−1 for the final 60m. What is the average speed of the baton in ms−1?
The average speed of the baton can be determined by dividing the total distance travelled by the total time taken for that travelling.
\(Average\ Time = \frac{Total\ Distance}{Total\ Time}\)
First, we will find the total distance, by adding the distances travelled by both Mahiya and Mrinmoy, while carrying the baton.
\(Total\ Distance = Distance\ Travelled\ by\ Mahiya\ to\ pass\ the\ baton\ to\ Mrinmoy\ +\ Distance\ Travelled\ by\ Mrinmoy\ to\ pass\ the\ baton\ to\ Mahiya\ +\ Final\ Distance\ Travelled\ by\\ Mahiya\)Total Distance = 60 m + 120 m + 60 m = 240 m
Now, we will find the total time taken for this travelling. To find out the total time we will divide each distance travelled by the speed of the traveller during that distance:
\(Total\ Time = \frac{60\ m}{6\ m/s}+\frac{120\ m}{4\ m/s}+\frac{60\ m}{3\ m/s}\\\\Total\ Time = 10\ s\ +\ 30\ s\ +\ 20\ s\)
Total Time = 60 s
Now, we finally find the average speed of the baton by using the formula:
\(Average\ Time = \frac{Total\ Distance}{Total\ Time}\\\\Average\ Time = \frac{240\ m}{60\ s}\)
Average Speed = 4 ms⁻¹

What is the fuel for the nuclear fusion reaction that occurs in the Sun?
A. helium
B. oxygen
C. plutonium
D. hydrogen
Hydrogen is the fuel for the nuclear fusion reaction that occurs in the Sun, therefore the correct answer is option D.
What is nuclear fusion?A reaction known as nuclear fusion occurs when two or more atomic nuclei combine to create new atomic and subatomic particles. Energy is released or absorbed depending on how much mass there is between the reactants and products.
The fusion of hydrogen to form helium is the main source of energy for the sun and other stars of a similar size.
The nuclear force, which brings protons and neutrons together, and the Coulomb force, which makes protons repel one another, interact to produce the energy release associated with the fusion of light elements. Despite being positively charged and repel one another due to the Coulomb force, protons can still stick together, proving the existence of a different, more localized force known as nuclear attraction.
Thus, The correct answer is option D because hydrogen serves as the fuel for the nuclear fusion reaction that takes place in the sun.

When compared with inner planets, the outer planets are relatively farther from the sun and have a shorter year.
The outer planets are relatively closer to the sun and have a longer year than the inner planets.
The outer planets are relatively closer to the sun and have a shorter year than the inner planets.
Answer:
When compared with inner planets, the outer planets are relatively farther from the sun and have a longer year.
Explanation:
The inner planets are Mercury, Venus, Earth, and Mars. The outer planets are Jupiter, Saturn, Uranus, and Neptune. The inner planets are inner, compared to the others in distance from the Sun-they are closer than the outer planets to the sun. A year is how long a planet takes to orbit the Sun. The further away, the larger the orbit. The larger the orbit, the more time it takes for a planet to orbit the Sun. It is the same concept as you traveling 2 miles versus 200 miles. The longer distance takes the longer time. The time/distance concept rules out the second answer choice, the closer/farther info rules out the third answer, and both information rules out the last answer choice. Through both logic and the process of elimination, the only correct answer is the first one.

Explore the intricacies and conceptual challenges of the Holographic Principle in the context of the AdS/CFT correspondence. Investigate the fundamental ideas behind the holographic duality proposed by Juan Maldacena, which suggests an equivalence between a higher-dimensional gravitational theory and a lower-dimensional quantum field theory. Analyze the mathematical foundations and implications of this principle, including the idea that all the information contained within a region of space can be encoded on its boundary. Assess the potential revolutionary impact of the Holographic Principle on our understanding of quantum gravity, black holes, and the nature of spacetime itself.
Answer:
The Holographic Principle, proposed by physicist Gerard 't Hooft and further developed by Juan Maldacena, is a fascinating concept in theoretical physics that has sparked significant interest and research. In the context of the AdS/CFT correspondence, it suggests that a gravitational theory in a higher-dimensional space can be mathematically equivalent to a quantum field theory in a lower-dimensional space.
At the heart of the Holographic Principle is the idea that the information and dynamics of a higher-dimensional theory can be fully captured by its boundary, implying that the entire bulk can be "holographically" encoded on the boundary. This concept challenges our conventional understanding of the relationship between space, gravity, and quantum mechanics.
The holographic duality proposed by Maldacena specifically relates a gravitational theory in Anti-de Sitter space (AdS) with a conformal field theory (CFT) in one fewer dimension. In this correspondence, the gravitational theory describes a curved space-time with gravity, while the CFT is a quantum field theory without gravity but living on the boundary of the AdS space. The holographic duality suggests that the two theories are mathematically equivalent and provide equivalent descriptions of the same physical phenomena.
The mathematical foundations of the AdS/CFT correspondence involve advanced concepts from string theory and quantum field theory. String theory postulates that fundamental particles are not point-like entities but rather tiny vibrating strings. By considering these strings propagating in a higher-dimensional space, theorists discovered that they naturally give rise to gravity. The holographic duality emerged as a surprising consequence of studying string theory in the AdS space.
The implications of the Holographic Principle are profound. First and foremost, it suggests a deep connection between gravity and quantum mechanics, two fundamental pillars of modern physics that have been notoriously difficult to reconcile. The holographic duality provides a framework to study strongly interacting quantum systems in terms of gravity, enabling insights into the nature of black holes, the behavior of matter in extreme conditions, and other phenomena that are challenging to analyze using traditional methods.
The Holographic Principle also has potential implications for our understanding of black holes. It proposes that the information that falls into a black hole is not destroyed, as suggested by the Hawking radiation phenomenon, but rather encoded on its event horizon. This idea, known as the "holographic encoding of information," has stirred intense debates and ongoing research in the field of black hole information paradox.
Furthermore, the Holographic Principle challenges our traditional notions of spacetime. It suggests that spacetime, as we perceive it, might emerge as an approximation or an emergent property from a more fundamental description involving quantum information. This notion aligns with the concept of "entanglement entropy," which measures the entanglement between quantum states and has been linked to the geometry of spacetime.
The potential revolutionary impact of the Holographic Principle lies in its potential to provide a unified framework for understanding quantum gravity and resolving long-standing mysteries in theoretical physics. It opens new avenues for studying the nature of black holes, the behavior of matter in extreme conditions, and the fundamental structure of the universe. However, it is important to note that the Holographic Principle is still an area of active research, and many aspects of its implications and applications continue to be explored and refined by physicists.
