in the formation of gneiss from a granite protolith, distinctive compositional bands form because of

a) The initial momentum of the gold nucleus is zero since it is at rest. b) the final momentum of the alpha particle will be \(p' = -1.91 x 10^-19 kg m/s\). c) the final momentum of the gold nucleus, long after it interacts with the alpha particle will be \(1.91 x 10^-19 kg m/s\)

The momentum of the alpha particle can be calculated using the formula p = mv, where m is the mass and v is the velocity. Since the alpha particle is moving in the +x direction, its velocity is positive. The mass of the alpha particle can be calculated by adding the masses of the two protons and two neutrons, which gives a total mass of 4.0026 atomic mass units (u).

Using the conversion factor of 1 \(u = 1.661 x 10^-27 kg,\)

The mass of the alpha particle is approximately \(6.64 x 10^-27 kg.\)

Therefore, the initial momentum of the alpha particle can be calculated by multiplying its mass by its velocity, which gives \(p = (6.64 x 10^-27 kg)(v)\).

Since the kinetic energy of the alpha particle is given as 10 MeV, we can use the formula KE = 1/2 mv^2 to calculate its velocity.

Rearranging the formula, we get\(v = sqrt(2KE/m).\)

Substituting the values, we get \(v = sqrt[(2 x 10^6 eV)(1.6 x 10^-19 J/eV)/(6.64 x 10^-27 kg)] = 2.88 x 10^7 m/s\). Therefore, the initial momentum of the alpha particle is\(p = (6.64 x 10^-27 kg)(2.88 x 10^7 m/s) = 1.91 x 10^-19 kg m/s.\)

b) After interacting with the gold nucleus, the alpha particle will experience a force due to the electromagnetic repulsion between the positively charged protons in both nuclei. This force will cause the alpha particle to deviate from its initial path and change its direction of motion.

However, the total momentum of the system will remain conserved, which means that the final momentum of the alpha particle will be equal in magnitude but opposite in direction to its initial momentum. Therefore, the final momentum of the alpha particle will be\(p' = -1.91 x 10^-19 kg m/s.\)

c) Similar to the alpha particle, the gold nucleus will also experience a force due to the electromagnetic repulsion with the alpha particle. However, since the mass of the gold nucleus is much larger than the mass of the alpha particle, its motion will be less affected by the collision. As a result, the final momentum of the gold nucleus will be almost equal to its initial momentum, which is zero.

However, there will be a slight recoil motion in the opposite direction to the alpha particle, which will result in a small final momentum. The magnitude of this momentum can be calculated using the conservation of momentum formula, which gives

\(p' = -p = -(-1.91 x 10^-19 kg m/s) = 1.91 x 10^-19 kg m/s\).

Therefore, the final momentum of the gold nucleus will be approximately \(1.91 x 10^-19 kg m/s\) in the opposite direction to the alpha particle.

Due to its size compared to other terrestrial planets, Earth has a lot of internal heat retained. This heat maintains the core's molten state and stimulates geological activity.

Condensed materials are used to create terrestrial planets. Therefore, the initial step in controlling the volatile content of the terrestrial planet is condensation from a heated gas. Refractory materials condense first during the early hot stage of cooling, while volatile elements do so later during the cool stage. Condensed matter may move toward or away from the star in addition to sinking to the nebula's equatorial plane and eventually becoming planets. Condensation will stop at the T Tauri stage of the mother star when the gaseous stages are driven off by the powerful solar wind, and the condensed components at this time will become the raw materials for terrestrial planets.

The statement is true because inputs into a lake, such as runoff and precipitation, must equal outputs, such as evaporation and outlets, in order to maintain a stable water balance.

If inputs exceed outputs, the water level in the lake will rise, potentially leading to flooding or other environmental problems. If outputs exceed inputs, the water level will decrease, potentially leading to drought conditions or other ecological imbalances.

Therefore, it is important to understand and manage the water balance of lakes and other bodies of water, particularly in regions that are prone to water scarcity or environmental degradation.

The intensity of the earthquake in terms of the Modified Mercalli Intensity Scale would depend on the extent of the damage caused.

The Modified Mercalli Intensity Scale (MMI) measures the intensity of an earthquake based on the observed effects and damage it causes. It assesses the impact on structures, infrastructure, and the environment. In the given scenario, the serious damage to reinforced masonry and the breaking of underground pipes indicate a significant impact.

The specific intensity level on the MMI scale would require more detailed information, such as the extent of damage, building type, and ground conditions. The scale ranges from I (not felt) to XII (destruction). Without further information, it is challenging to determine the exact intensity level.

However, based on the described serious damage, it suggests a moderate to strong intensity, possibly in the range of IV (moderate) to VIII (severe) on the MMI scale.

Rough, angular stones  material, when dry, tends to form the greatest angle of repose. In this case Option B is correct

A granular material's angle of repose, also known as its critical angle of repose, is the steepest angle of descent or dip that the material can have with respect to the horizontal plane without collapsing.

The slope face's material is on the verge of sliding at this angle. The angle of repose can be anywhere between 0° and 90°. The angle of repose is influenced by the material's morphology; for example, rough, interlocking sands can be piled more steeply than smooth, rounded sand grains

The most significant issue impacting Brazil is Option B. Illegal logging.

Illegal logging is the felling, cutting down, or removal of trees from forests, land that is legally designated to remain forested or government-owned land without permission, license, or authorization from either the landowner or relevant authorities. Illegal logging is typically associated with organized crime and is considered one of the most severe threats to tropical forests worldwide.

In Brazil, the Amazon rainforest, which accounts for about half of the world's tropical forest area, is the primary target of illegal logging. The Amazon rainforest is known for its biodiversity and as the lungs of the earth, producing about 20% of the world's oxygen. It also contributes significantly to global weather systems. The impacts of illegal logging on the Amazon are numerous and severe.

Deforestation leads to the displacement of indigenous communities, soil erosion, landslides, and the destruction of habitat, which can lead to the extinction of endangered species, including plants and animals. It also leads to climate change since deforestation contributes to carbon emissions.

The Brazilian government has implemented measures to curb illegal logging and reduce deforestation, such as increased law enforcement, forest monitoring, and supporting indigenous land rights. However, these efforts face several challenges, including corruption, weak enforcement of laws, and the high demand for illegal timber. Therefore, the correct option is B.
