Answer:

1,437.33

Explanation:

Volume of a sphere = 4/3πr³

π = 22/7

r = 7

Volume of a sphere = 4/3πr³

= 4/3 * 22/7 * 7³

= 4/3 * 22/7 * 7 * 7 * 7

= (4 * 22 * 7 * 7 * 7) / (3 * 7)

= 30,184/21

= 1437.3333333333

Volume of a sphere = 1,437.33

Without the specific information or visualization of the graph, the effect of doubling the distance from the center cannot be determined.

The given question refers to a rotation curve graph, which shows the relationship between the orbital speed and distance from the center of the merry-go-round. However, since the specific characteristics of the graph are not provided, such as its shape or trend, it is impossible to draw a definitive conclusion about the effect of doubling the distance. The answer emphasizes the need for more information or visualization of the graph to determine the relationship between distance and orbital speed accurately.

This is not true of environmental geology, i.e.  it is concerned with developing methods to prevent natural disasters from occurring.

Environmental geology, like hydrogeology, is an applied discipline focused on using geological concepts to solve environmental issues that humans have caused. It is a multidisciplinary area that has a tight relationship with engineering geology and, to a lesser extent, with environmental geography.

Environmental geology is the use of geological knowledge to resolve disputes, reduce the possibility of environmental deterioration, or increase the likelihood of favourable circumstances arising from the usage of the natural and modified environment. Natural resources and the environment are under severe stress as a result of global industrialization and population growth, which puts them at the forefront of global challenges.

The true statement is earthquake magnitude is based on ground motion recorded by a seismograph; intensity is based on the amount of damage produced. Option B is the answer.

The correct answer to the second question is B. The  could have resulted in an even greater death toll, but for the timely warnings issued immediately after the earthquake.

A abrupt shaking or trembling of the Earth's crust is known as an earthquake, and it is typically brought on by the movement of tectonic plates. These plates are continually shifting, bumping into one another, and sliding past one another. When this happens, seismic waves are created that travel through the Earth's crust and cause the ground to tremble.

The Richter scale, which is based on the amplitude of the seismic waves captured by seismographs, is used to determine an earthquake's magnitude. In addition to causing additional damage and fatalities, landslides, tsunamis, and liquefaction are secondary hazards that can be brought on by earthquakes.

The tsunami event of December 26, event involved a magnitude 9.1 earthquake that lasted for several minutes and caused a series of destructive tsunamis that affected many countries in the Indian Ocean, not just Sumatra.

14D | 3.2 | 5.4 million

WOO | 5.4 | 7.4 million

98 | 7.4 | 6.5 million

CUD | 6.5 | 4.2 million

a) Calculation:

i) The total population:

Total population = Population of 14D + Population of WOO + Population of 98 + Population of CUD

Total population = 3.2 + 5.4 + 7.4 + 6.5

Total population = 22.5 million

ii) The total land area:

Total land area = Land area of 14D + Land area of WOO + Land area of 98 + Land area of CUD

Total land area = 5.4 + 7.4 + 6.5 + 4.2

Total land area = 23.5 million km²

The correct answer to the given question is :Clear, calm, dry night  .It is important to understand temperature inversions as they play a significant role in the weather conditions of a region.

A temperature inversion is defined as a layer of the atmosphere where the temperature increases with height rather than decreasing. This phenomenon is typically associated with clear, calm, and dry nights .When the sky is clear and the wind is calm, heat radiates from the earth's surface into the atmosphere. During this process, the temperature of the air in contact with the ground decreases, resulting in the coldest temperature being found near the ground .In contrast, cloudy and damp nights do not support temperature inversions since the clouds keep the heat from radiating into the atmosphere.

Windy nights, on the other hand, mix the air, causing the cold air to mix with the warmer air, which eliminates the temperature inversion .As for why temperature inversions are important, they can impact air quality and the formation of weather patterns. Temperature inversions trap pollutants in the lower atmosphere, leading to a rise in smog. They also play a role in the formation of fog, as they create a stable layer of air that allows moisture to accumulate.

Bellerophon's likely formation and evolution scenario involves its birth in the protoplanetary disk of its parent star, where gas and dust particles slowly accumulated and formed planetesimals.

These planetesimals collided and merged, gradually growing into larger bodies, eventually reaching a critical mass and becoming a protoplanet. As Bellerophon continued to accrete material, it became surrounded by a thick atmosphere of gas and dust. Over time, the heat generated by the radioactive decay of elements within its core caused it to differentiate into a rocky core and a gaseous envelope.

The gravitational interaction between Bellerophon and its surrounding disk eventually caused it to migrate inward toward its parent star. During this time, it likely experienced a series of gravitational perturbations from other planets or planetesimals in the system, leading to changes in its orbit and potentially even collisions with other bodies.

When in geostrophic balance, the winds are strongest where (b) the isobars are closest together. Geostrophic balance occurs when the pressure gradient force and the Coriolis force are in equilibrium.

When in geostrophic balance, the winds are strongest where the isobars are closest together. Geostrophic balance is a state where the pressure gradient force and the Coriolis force are in balance. This results in wind flowing parallel to the isobars at a constant speed. The closer the isobars are together, the greater the pressure gradient force, which leads to stronger winds. Therefore, option b is the correct answer. It is important to note that geostrophic balance is usually found at high altitudes and is used to understand large-scale atmospheric circulation. On smaller scales, other forces such as friction come into play and can affect the wind direction and strength. When the isobars are closely spaced, it indicates a steep pressure gradient, meaning the pressure changes rapidly over a short distance. This results in stronger winds due to the increased force acting on the air parcels. In contrast, when isobars are farther apart, the pressure gradient is weaker, leading to weaker winds.
