A student is playing with marbles. He rolls a purple marble, which strikes a green marble that is at rest. After the collision, the green marble rolls away from the student. The purple marble rolls back toward him.
Why does the purple marble roll back toward the student? Explain your response in terms of Newton’s third law.
Answers
Answer:YOUR MOM LOL
Explanation: THIS IS THE ANSWER... NO FATHER LOL
Newton's third law states that every action has an equal and opposite reaction.
In the context of the scenario with the marbles, when the purple marble strikes the green marble, the green marble exerts an equal and opposite force toward the purple marble, which is why it rolls back toward him.
Transfer of momentum takes place from the green marble back to the purple marble. This can be explained in terms of Newton's third law, because the forces between two marbles are equal and opposite in direction.

Answers
Answer:
Explanation: COMPOST BIN
WHAT IS A COMPOST BIN?
A compost bin is a container into which you place organic waste to turn into compost (organic material) over time.
Most compost bins are designed to hasten the decomposition of organic matter through proper aeration and moisture retention. With the proper combination of air and moisture, ideal conditions are produced for the activity of aerobic organisms responsible for the high temperatures that transform the organic materials into compost
Read on to find out how to start a compost bin, DIY compost bin ideas, and more tips for beginners.
The decomposition process will eventually take place over time in a compost "pile" or "heap," even without any housing to contain the matter. However, a compost bin is worth it because it helps speed up decomposition and keeps the area neat. Some bins are continuous, meaning you can keep adding waste to them, while others create batches of compost with a set mix of ingredients you add all at once. Depending on the style of compost bin you choose, bins can also have the advantage of making it harder for rats to get at your compost. This is true of the tumbler type, for example.
CHOOSING THE RIGHT BIN
Select the right bin for your composting needs. You can make an inexpensive compost container out of almost any container or material. Some ideas include:
Plastic storage container
Plastic bucket
Trash cans
Straw bales
Lumber
Branches harvested from the woods
Stone
Cinder blocks
Wire fencing
Ceramic (also popular for a kitchen countertop compost bin)
The best bin, however, is one you can easily turn or rotate consistently to control odors and make sure all the materials decompose. This is especially important for aerobic composting (more information below). A tumbler composting bin is pricey, but you can DIY one from barrels and sawhorses. You can turn compost with a rake or shovel in a non-rotating bin, it just takes more labor to do so.

Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

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.

Answer: Option c
Explanation: Wind has kinetic energy to move objects from their places. It is vastly used across the world for the production of electricity.
By turning the kinetic energy of moving air into electrical, the wind is used to generate power. Wind drives the rotor blades of contemporary wind turbines, which transform kinetic energy into rotational energy. A shaft transmits this rotational energy to the generator, which generates electrical energy. More than a century ago, the first wind turbines appeared. After the electric generator was developed in the 1830s, engineers began experimenting with harnessing wind power to create electricity. However, modern wind power is thought to have been invented in Denmark, where horizontal-axis wind turbines were built in 1891 and a 22.8-meter wind turbine started operating in 1897. Wind power generation occurred in the United Kingdom and the United States in 1887 and 1888.

What is pressure gradient?In atmospheric science, the pressure gradient ( generally of air but more generally of any fluid) is a physical volume that describes in which direction and at what rate the pressure increases the most fleetly around a particular position. SI Unit of pressure gradient is Pascal per meter( Pa/ m). Mathematically, it's the gradient of pressure as a function of position.
As temperature of air rises, the volume of air increases, that is, density of air decreases. As a result, pressure at high temperature area also decreases. Air generally moves from an area at high pressure to a area of low pressure. So following pressure gradient , air moves from low temperature area to high temperature area.
According to given data, temperate of area X is greater than both area Y and Area Z.

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.
