No, I don't agree with the friend.
Explanation:
I don't agree because the energy doesn't just "disappear it's converted to kinetic energy. due to the friction some of the energy in the system is converted to heat energy making it look like it "disappeared".
Energy can't be created nor destroyed so it definitely can't just disappear though it can be converted or transformed.

My question:
As an analogy of a circuit with resistance, think of an obstacle race . Which parts of a circuit do the obstacles represent? which part of the circuit do the people respresent?
Answers
In an analogy of a circuit with a resistance to an obstacle race, we can consider various elements of the race as representative of different components of the circuit.Obstacles, Track or Route, Participants, Start and Finish Line.
Obstacles: The obstacles in the race represent the resistors in a circuit. Just as resistors impede the flow of current in a circuit, obstacles in the race create hurdles that slow down the participants. The difficulty or magnitude of the obstacles can be equated to the resistance value of the resistors in a circuit.
Track or Route: The race track or route itself can be seen as the conductive path in a circuit. It provides a pathway for the participants to move and complete the race. Similarly, the conductive path in a circuit allows the flow of current from the power source to the load.
Participants: The people participating in the race represent the flow of electrons in a circuit. Just as the participants move through the obstacles in the race, electrons move through the resistors in a circuit. The rate at which participants complete the race can be compared to the current flowing through the circuit.
Start and Finish Line: The start and finish line of the race correspond to the terminals of a circuit. The start line represents the positive terminal, where the participants begin their journey, and the finish line represents the negative terminal, where the race concludes.

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.
Answers
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.

Describe 3 factors an engineer should take into consideration when choosing material for building the pipes in a pipeline
Gr. 8
Think it has something to do with Viscosity, Density, and Pressure but not sure what
Answers
Answer: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)
Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.
2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.
3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.
The things you said before about viscosity, density, and pressure are also correct. The correct answers are mainly talking about factors of the material being used in the pipes.

A driver is driving a 6371 kg lorry. After spotting a hazard, the driver applies the brakes. The lorry decelerates uniformly and comes to a stop 60 m after the brakes are applied. Estimate the braking force needed to stop the lorry.
Answers
Answer:
The estimated braking force needed to stop the lorry is zero, based on the given information and calculations. However, it's important to note that this result is likely not accurate, as some force is required to stop a moving object. It's possible that additional information or calculations are needed to obtain a more realistic estimate of the braking force.
Explanation:
To estimate the braking force needed to stop the lorry, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).
In this case, the lorry decelerates uniformly, so the acceleration is constant. The initial velocity is assumed to be zero since the lorry comes to a stop. The final velocity is also zero. Therefore, we can use the equation:
Final velocity squared (vf^2) = Initial velocity squared (vi^2) + 2 * acceleration (a) * distance (d)
Since vi = 0 and vf = 0, the equation simplifies to:
0 = 0 + 2 * a * d
Solving for acceleration (a), we have:
2 * a * d = 0
a = 0
Since the acceleration is zero, it means that the braking force needed to stop the lorry is also zero. This is likely not an accurate result as some force is required to stop the lorry. It's possible that additional information or calculations are needed to accurately estimate the braking force.
The braking force required to stop a 6371 kg lorry after spotting a hazard and applying the brakes is what the question is asking for. The lorry decelerates uniformly and comes to a stop 60 meters after the brakes are applied.
The following steps will guide you on how to calculate the braking force:
Step 1: Determine the mass of the lorry which is 6371 kg. This will be denoted as m.
Step 2: Determine the distance travelled by the lorry, which is 60 m.
Step 3: Determine the time taken by the lorry to stop. This can be done by using the formula for uniform deceleration, which is a = (v-u)/t where v is the final velocity, u is the initial velocity and a is the uniform deceleration. Since the lorry comes to a stop, its final velocity is zero and its initial velocity is unknown.
However, we can assume that the lorry was initially travelling at a constant speed before spotting the hazard. Therefore, we can assume that the initial velocity was equal to the average velocity of the lorry before the brakes were applied.
This can be calculated using the formula v = d/t where d is the distance travelled and t is the time taken. The average velocity can therefore be calculated as follows: v = d/t = 60 m/t
Step 4: Rearrange the formula for uniform deceleration, a = (v-u)/t, to find u which is the initial velocity. Since the lorry comes to a stop, we know that v = 0.
Therefore: u = v - at where a is the uniform deceleration and t is the time taken to stop which is also equal to the time taken for the lorry to travel the distance of 60 meters. Substituting for v, we get: u = - at
Step 5: Calculate the acceleration of the lorry using the formula a = (v-u)/t. Since the final velocity is zero, we get: a = -u/t = -(-at)/t = a The acceleration is negative since the lorry is decelerating.
Step 6: Calculate the braking force using the formula F = ma where F is the braking force and m is the mass of the lorry. Therefore: F = ma = (-ma) since a is negative = (-6371 kg) (a) Therefore, the braking force required to stop the lorry is -6371a N where a is the uniform deceleration calculated in Step 5.

Answers
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.

How does the sport curling relate to Newton’s Second Law of Motion?
Answers
Curling is a sport in which players slide stones across a distance of ice toward a target area. The purpose is to accumulate the loftiest score for a game by making monuments rest closest to the center of the target at the end of each side. There are two brigades. Each platoon is trying to keep the other platoon's monuments down from the target by knocking their monuments out of the way.
Newton's Second Law " The acceleration of an object is directly commensurable to the net force acting on it and is equally commensurable to its mass. The direction of the acceleration is in the same direction as the net force acting on an object." This relates to the formula F = ma. The mass of the determinedness monuments in curling is 38 to 44 pounds or 17.3 to 20 kg. The thing of the sweepers is to control the acceleration of the gravestone by reducing disunion on the ice, which affects the force with which the gravestone is suitable to impact the other monuments.

https://brainly.com/question/25545050
Second law-
Newtons second law occurs during curling when the delivery man, such as Glenn Howard, applies force to the stone pushing down the lane to the target while friction pulls it back the other way to a slow stop. The mass of the stone is 40lbs and the net force of everything on item will give you its slowly decreasing acceleration. Otherwise known as, F=mA.
Third law-
This law can be exerted in the sport of curling when the force behind a stone being delivered is transferred into another stone that is at rest, where the energy and force of one moving object is transferred to another. This almost completely stops the original stone, and gives some speed to the stone(s) it collides with.

what reasons can u give for the difference in speed for each cars?
Answers
Answer:
There are many factors that can affect the speed of a car, including:
Engine size and power: A car with a larger and more powerful engine will be able to accelerate faster and reach higher speeds than a car with a smaller engine.
Transmission: Cars with manual transmissions typically have better acceleration than those with automatic transmissions because the driver can control the gears and timing of the shift.
Aerodynamics: Cars that are designed with aerodynamic shapes and features, such as a low profile or smooth body, will be able to reach higher speeds and maintain them more easily than cars with less aerodynamic designs.
Weight: Cars that are lighter in weight will be able to accelerate faster and reach higher speeds than cars that are heavier.
Tires: Cars with wider tires will typically have more grip and better traction, which can allow them to reach higher speeds and handle better.
Suspension: Cars with better suspension systems will be able to maintain stability at high speeds and handle better.
Driving technique: The way a driver handles a car can also affect its speed, a skilled driver can make the most of the car's performance and get a better outcome.
Answer:
distance and time
Explanation:
Speed depends upon distance and time. So, if the distance is long but time is less, the speed will be high. On the other hand, if the distance is short and time is enough, the speed of the car will be slow.

Explain what happens as the heart grows bigger.
Answers
Initially, the heart may grow bigger as a compensatory mechanism to try to keep up with increased demands for blood and oxygen. For example, if a person engages in regular exercise, their heart may enlarge to accommodate the increased demand for blood and oxygen to the muscles.
However, if the heart continues to grow over time, it can become less efficient at pumping blood and may develop structural abnormalities that increase the risk of heart failure, arrhythmias, and other complications.
In some cases, cardiac hypertrophy may be reversible if the underlying cause is treated, such as by managing high blood pressure or heart disease. However, if left untreated, hypertrophy can lead to irreversible damage to the heart muscle and may require more aggressive interventions, such as medication, surgery, or other medical procedures to manage the condition.
