When a rock is thrown from an asteroid in space, it will continue to travel until an external force acts on it. This means that the rock will not come back to the asteroid if it is thrown with sufficient velocity.
The speed required to achieve this will depend on the mass of the rock and the gravitational force between the rock and the asteroid. To calculate the required velocity, we can use the escape velocity equation :v = √(2GM/r)Where v is the escape velocity, G is the gravitational constant, M is the mass of the asteroid, and r is the distance between the rock and the center of the asteroid.
Using the given values, we can calculate the escape velocity as follows :v = √(2 * 6.6743 x 10^-11 * 10^18 / 200) ≈ 10.43 m/s This means that the rock needs to be thrown from the asteroid with a velocity of at least 10.43 m/s in order to never come back and end up traveling at a speed of 10 m/s when it is very far away. Any velocity greater than this will also work .In conclusion, to throw a rock from an asteroid so that it never comes back and ends up traveling at a speed of 10 m/s when it is very far away, the rock needs to be thrown with a velocity of at least 10.43 m/s.

My son, daughter and dog have written yet another weather model. It's quite impressive, but they are having an issue with their microphysics scheme creating its own convection, thus indicating all sorts of fun weather where there isn't any. What should I tell them to help them with their dilemma?
A. Perhaps they should consider another hobby?
B. Try adding a complex cloud scheme.
C. Need better data assimilation techniques.
D.They should use the BMJ CP scheme.
My son, daughter, and dog have written yet another weather model. It's quite impressive, but they are having an issue with their microphysics scheme creating its own convection, thus indicating all sorts of fun weather where there isn't any. The answer to this question is "B. Try adding a complex cloud scheme".
Here's why: It is common for weather models to encounter issues when calculating weather variables that are associated with complex atmospheric processes. When they are having issues with their microphysics scheme creating its own convection, thus indicating all sorts of fun weather where there isn't any, it might help to add a complex cloud scheme. In this case, the problem seems to be with the fact that the microphysics scheme is generating its own convection, indicating fun weather that is not present. If a complex cloud scheme is added, it might help reduce these incorrect forecasts.
Other schemes, such as the BMJ CP scheme, may have similar problems or fail to work entirely. As a result, option D is not a valid option. Option A is also not recommended because it implies that the efforts of the children are fruitless. Finally, while better data assimilation techniques may improve the accuracy of their model, it does not appear to be directly related to their current dilemma. Thus, option C is incorrect.

the most common hazard(s) are: what tectonic/geologic settings do they form in?
The most common hazards caused by tectonic/geologic activities are earthquakes, volcanic eruptions, and tsunamis. These natural phenomena are primarily associated with plate tectonics and geologic activity in subduction zones and along fault lines.
Earthquakes are a common hazard that occurs due to the movement of tectonic plates. The majority of earthquakes occur at the boundaries of tectonic plates, including divergent, convergent, and transform boundaries. These plates move against each other, and the friction results in earthquakes. The convergence of two plates, in particular, can lead to the formation of subduction zones. When an oceanic plate is subducted under a continental plate, it can result in the formation of volcanic arcs and trenches.
Volcanic eruptions, another common hazard, are often caused by tectonic activity. The movement of plates can lead to the formation of a magma chamber, which can then result in an eruption. Volcanoes can also occur at divergent plate boundaries. Tsunamis, on the other hand, are often triggered by earthquakes. When an earthquake occurs under the ocean, it can cause a sudden displacement of water, leading to the formation of a tsunami.
The above mentioned hazards form in tectonic/geologic settings such as plate boundaries and subduction zones, where tectonic plates are either diverging, converging, or sliding past each other.

11. True
The joints expressed by dip and direction is a true statement. Joints are formed due to the internal forces of a rock. These forces include tectonic pressure, cooling and contraction, and stress caused by erosion. Dip refers to the angle of the fracture in relation to the horizontal plane,
while the direction indicates the direction of the fracture.
12. True
The statement "Hexagonal or columnar jointing is due to compression stress" is false. This is because hexagonal or columnar jointing is due to the contraction of lava flows or cooling and contraction of igneous rocks. This is why they are often found in igneous rocks such as basalt.
