Answer:
Intensity depends on the distance form the ground and source of energy.
Explanation:
Earth quake that has an intensity of 1.5 on the Richter scale can be detected only through the seismograph. The earthquake with an intensity of 0 levels on the Richter scale that is below micro will not be felt or rarely felt in scale. This can be defied by the Richter scale formula of R=log(IcIn), Ic is the intensity and In is the intensity if the standards earthquake. Hence the difference will be R2−R1=log(I2I1)Choose the correct explanation why the following statement makes sense (or is clearly true) or does not make sense (or is clearly false):
Gravitational waves are best observed with the Hubble Space Telescope.
Choose the correct explanation why the following statement makes sense (or is clearly true) or does not make sense (or is clearly false):
Gravitational waves are best observed with the Hubble Space Telescope.
a. This statement does not make sense. We do not have technologies for direct observations of gravitational waves.
b. This statement is clearly true. The HST firstly observed the gravitational waves from the merge of two black holes in 2015.
c. This statement does make sense. As a space telescope, the HST can be used as an interferometer with a very long base and can detect tiny distortions of space.
d. This statement is clearly false. The HST observes visible and infrared light, not gravitational waves.
Answer: This statement is clearly false. The HST observes visible and infrared light, not gravitational waves.
Explanation:
Gravitational waves refers to ripples in spacetime. The statement that gravitational waves are best observed with the Hubble Space Telescope is false.
This is because the Hubble Space Telescope is used in observing visible and infrared light, not gravitational waves. The telescope has helped scientists to understand how the planets are formed.

A015) Strike-Slip Faults - Carrizo Plain, CA. The Problem 15 placemarks highlight a stream near the Carrizo Plain in California that has been offset along the San Andreas fault zone (the San Andreas Fault is a strike-slip fault that forms a transform plate boundary between the North American and Pacific plates). Given the offset stream in the view, what is the sense of offset along this fault
Answer:
Right lateral.
Explanation:
San Andrea's fault makes a tri-junctions between the North American and the pacific plate. Being 1300 km long this fault and extends to 25 km in depth. It has a northwestern-southeastern trend and is classified as a right-lateral or dextral fault.All of the following describe likely air mass source regions in the summer EXCEPT: Group of answer choices the subtropical Western Atlantic Ocean Northern Mexico the Central United States the subtropical Eastern Pacific Ocean
Answer: the Central United States
Explanation:
Air mass regions in the summer are usually around the middle latitudes of the Earth which means that they are closer to the Equator. This includes subtropical regions of the world including the subtropical Eastern Pacific and Western Atlantic Oceans.
Northern Mexico is also quite close to the middle latitudes so the most logical answer from the options is Central U.S. because it is the furthest from the equator and the middle latitudes of Earth.

explain why some children in India do not get access to education, even though the Indian government have made education compulsory and free for all children 6-14 years of age.
Answer:
Explanation:
Search out Greg Mortenson on the internet. With the help of a ghost writer, he wrote Three Cups of Tea. It has moved a great many people including me. It is the story of a mountain climber who wandered aimlessly in the a poor region of Pakistan (but the same comments apply to India). He collapsed in a village where, had he landed anywhere else, he likely would have been left to die.
Eventually after dealing with all sorts of problems (including the Taliban), he comes to realize that the only way out of poverty the people of this village endured (and many others like it) was education. From that moment on, he dedicated himself to raising money to build schools in areas like the one that found him. His firm belief was that Education was the only answer.
I think the answer to your question is isolation. Some areas of India are just too isolated and too poor to do anything about education. A whole much better description is in 3 cups of tea and if you are serious about your question, you will find it and read it.
A thermally-driven circulation develops because: Group of answer choices in cold, dense air, isobars bunch closer together, while in adjacent warm, less dense air, they spread farther apart. aloft, high pressure develops in cold air regions while low pressure develops in warm air regions. at the surface, high pressure develops in warm air regions while low pressure develops in cold air regions. cold air rises and warm air sinks.
Answer:
Aloft high pressure develops in cold air regions while low pressure develops in warm air regions
Explanation:
A thermally-driven circulation, or thermals are the movement of warm air that move to a higher level due to the buoyancy forces acting on them. That is due to the difference in densities between the warmed and cool air
Given that pressure = Density, ρ × Gravity, g × Height, h, we have that decrease in pressure (low pressure) is due to low density, therefore, the warm air having low pressure, moves upwards, due to their low density
Therefore, the best option is aloft, (as we move higher), high pressure develops in cold air regions while low pressure develops in warm air regions

mối quan hệ giữa quá trình nội lực và ngoại lực
Answer:
The importance of categorizing a force as being either internal or external is related to the ability of that type of force to change an object's total mechanical energy when it does work upon an object. When net work is done upon an object by an external force, the total mechanical energy (KE + PE) of that object is changed.
Explanation:
in vietamnise/
Tầm quan trọng của việc phân loại một lực là bên trong hoặc bên ngoài có liên quan đến khả năng của loại lực đó để thay đổi tổng năng lượng cơ học của một vật thể khi nó hoạt động trên một vật thể. Khi công việc ròng được thực hiện trên một đối tượng bởi một ngoại lực, tổng năng lượng cơ học (KE + PE) của đối tượng đó được thay đổi.
The particular name of an igneous rocks consisting of minerals is best determined using the chart in the lab book and noting:____.
(a) the presence of quartz and one other mineral.
(b) the presence of vesicles (gas pockets) in proportion with the presence of the mineral quartz.
(c) the relative color (light, intermediate, or dark) and the relative size of the minerals (phaneritic/aphanitic).
(d) whether the minerals present are metallic or non-metallic and then determining the streak on each mineral present.
Answer:
C, the relative color
Explanation:
Color indicates the composition of a rock or mineral. A felsic composition is indicated by light colors such as white or pink. Intermediate rocks or minerals have a medium color such as gray or an equal part of dark and light colored minerals . Mafic or ultramafic rocks or minerals are dark colored such as black or brown however they might also contain light colored minerals within them.

Discuss on the major problem of urban centres of ethiopia
Answer: Urban centers in Ethiopia are ridden by a variety of socio-economic issues such as illiteracy, unemployment, and especially poverty.
Explanation: They can also lack environmental management, lack of stability in infrastructure and buildings, as well as lack of investment in the local human population.
While there has been an increase in construction, the quality of construction itself has been poor as the government has felt pressure to rapidly build in order to meet demand and immediate needs. However this can mean very costly rehabilitation of the faulty construction in the future.
In addition, in urban Ethiopia, women out number men which has contributed to the poverty level as their main source of employment is agriculture.
Furthermore, many times there is only one main road within the urban centers which contributes to a lack of infrastructure and overcrowds the area.
Finally, there is also a lack of post secondary education and medical facilities.

Which statement best describes the difference of the mean of the two data sets?
A.
It is equal to about 0.5 times the mean absolute deviation of either data set.
B.
It is equal to about 1 times the mean absolute deviation of either data set.
C.
It is equal to about 1.5 times the mean absolute deviation of either data set.
D.
It is equal to about 2 times the mean absolute deviation of either data set.
Answer:
B.) It is equal to about 1 times the mean absolute deviation of either data set.
Explanation:
Given the scores :
Williams :
89,97, 78, 81, 91
Andre :
90, 74, 73, 87, 82
The mean scores :
Mean = ΣX / n
William's mean score = 436 / 5 = 87.2
Mean absolute deviation :
[|89-87.2| + |97-87.2| + |78-87.2| +|81-87.2| + |91-87.2|] / 5
William's mean absolute deviation = 6.16
Andre's mean score = 406 / 5 = 81.2
Andre's mean absolute deviation =
[|90-81.2| + |74-81.2| + |73-81.2| +|87-81.2| + |82-81.2|] / 5 = 6.16
Difference of the mean = 87.2 - 81.2 = 6
Mean absolute deviation of each dataset = 6.16
The closest relationship between the mean difference and the mean absolute deviation is :
Mean difference is about 1 times the mean absolute deviation
