In the diagram, FH2FG, GHHI, and FIIK. Which of the following statements must be true?
Answers
Question:
In the diagram, FH = 2FG, GH = HI, and FI = IK. Which of the following statements must be true? Select all that apply.
(a) FG = HI
(b) HI = IJ
(c) IK = 3FG
(d) FH = GI
(e) HJ = JK
(f) HK = 2GI
Answer:
(a) FG = HI
(c) IK = 3FG
(d) FH = GI
(f) HK = 2GI
Explanation:
The diagram to this question has been attached to this response.
From the question:
=> FH = 2FG
Let FG be x units
Then FH = 2x units -----------------------(*)
=> FH = FG + GH [Remember: FG = x units, FH = 2x units]
2x = x + GH
GH = x units
Also
=> GH = HI [Remember: GH = x units]
x = HI
HI = x units
=> FG = GH = HI = x units --------------------(i)
=> FI = FH + HI [Remember: FH = 2x units, HI = x units]
FI = 2x + x
FI = 3x units
=> FI = IK [Remember: FI = 3x units ]
IK = 3x units -----------------------------(ii)
Now lets go to the question
(a) Check if FG = HI
FG = HI = x units [from equation (i)]
∴ FG = HI
(b) Check if HI = IJ
HI = x units [from equation (i)]
IJ = y units [Not enough information to find the IJ]
∴ HI = x units may not be equal to IJ
(c) Check if IK = 3FG
IK = 3x units [from equation (ii)]
FG = x units [from equation (i)]
∴ IK = 3FG
(d) Check if FH = GI
FH = 2x units [from equation (*)]
GI = GH + HI [GH = x units, HI = x units from equation (i)]
GI = x + x = 2x units
∴ FH = GI
(e) Check if HJ = JK
HJ = HI + IJ
HJ = (x + y) units
JK = IK - IJ
JK = 3x - y
∴ HJ may not be equal to JK
(f) Check if HK = 2GI
HK = HI + IJ + JK [JK = (3x - y) as calculated in (e) above]
HK = x + y + (3x - y)
HK = 4x
2GI = GI + GI [GI = 2x units as calculated in (d) above]
2GI = 2x + 2x = 4x
∴ HK = 2GI

The terrestrial planets experience quakes, the gas giants do not.Terrestrial planets experience (or experienced) tectonic activity, gas giants do (or did) not.Activity in the molten interior of the terrestrial planets results (or resulted) in tectonic activity. Thus, option (a), (d), and (f) is correct.What is planets?
The term “planet” refers to a large celestial body that orbits around the sun, but the sun is a fixed point in place. The planets are different sizes, as smaller planets are Earth, Mercury, Mars, and Venus. The larger gas giant planets are Jupiter, Uranus, Neptune, and Saturn.
Heat loss is what drives tectonic activity. Earthquakes occur on terrestrial planets, but not on gas giants. Terrestrial planets have tectonic activity, while gas giants do not (or did not previously). Tectonic activity is caused (or derived from) activity in the molten interiors of the terrestrial planets.
Therefore, option (a), (d), and (f) is correct.

How does relative geographic scale differ from scale of data?
Answers
We have maps showing entire continents and maps showing all the houses in a small town. We have maps telling us information about the people living there, how land is used, or even the concentration of an endangered species. An important part of a map is the scale it uses, but that depends on the type of data we want to know. There are two types of scales used in geography: map scales and relative scales. Each has a very different function, yet both also can work together.
Map Scales
The scales used in mapping, usually noted in a lower corner of the page, employ relative distance. You couldn't expect a map to be an exact match to the landscape or you would need to unfold miles of paper. By creating a smaller image of the actual landscape, the map becomes a useful tool. However, the relationships between places on the map must remain consistent with reality. This is where the map scale comes in, to tell us what a certain distance on a map represents in real space.
A map can inform us of the scale it uses in three different ways.
A verbal scale can tell us in words, like ''one inch equals one mile.''
A fraction or ratio can compare the distances with the relationship of the map's distance to the actual distance, such as 1 inch:10 miles; 1:10; 1 inch:10 miles; or 1:10.
A graphic scale is one in which the scale is written as a graph with the representation of the distance marked at consistent intervals on the line. This means that each line segment equals a certain distance. These scales are great if you don't have a ruler or tape measure handy to measure the map. You can mark the scale on the edge of some scrap paper and hold it up to the map to figure out how far apart two points are.
Relative Scale
Don't let the term ''relative'' confuse you into thinking this type of scale deals with relative distance like with a map scale. Relative scales, also called scales of analysis, refer to the amount of detail included in the map and the size of the units at which we are looking. This is called the level of aggregation, or many details get lumped together on the map based on the unit size we are analyzing. It's basically details about a place one might use in a research project instead of distance.
The lower the level of aggregation, the more specific we get with the detail. It's like zooming in and out from a satellite image. If we zoom in, we are at a low elevation and see very specific details. We can see the roof of a house and individual cars.
The difference is the values on the map as compared to ground.
The main difference between geographic scale and scale of data is that geographic scale is a type of scale which can be used to show the geographical region. This type of scale is used in our daily life in various activities e.g. USGS topographic maps have a scale of 1:24,000. In this map, one inch on the map represents 24,000 inches in the real world while on the other hand, scale of data or Map scale refers to the relation between distance on a map with the distance on the ground e.g. 1:100000 scale map, where 1cm on the map equals 1 km on the ground.

A spacecraft orbiting Earth relies on solar panels that have an efficiency of 26% (percent of incoming energy the panels can convert) for power. The spacecraft has a battery to store energy for the half of isorbi the spacecraft is on the night side of the planet and incoming solar irradiance is 1367 W/m2. How big do the panels have to be at minimum if the spacecraft require 1000 W of power? Show your work.
Answers
Answer:
The solar panel should have a surface area with a size of 2.8 m^2
Explanation:
efficiency of solar panel = 26% = 0.26
solar irradiance = 1367 W/m^2
required power = 1000 W
area of panel = ?
The power that need to fall on the panel = 1000/0.26 = 3846.15 W
This power is gotten from the solar irridiance incident on the plate
The minimum area the plate must have to absorb this power must be
From
A = E/I
where
A is the area of the solar panel
E is the energy needed by the panel
I is the irridiance from the sun
substituting values, we have
A = 3846.15/1367 = 2.8 m^2

Refer to Animation: Greenhouse Effect. Which of the answer choices is false? Approximately 50% of the sun's light energy does not reach the surface of the Earth. The Earth radiates heat energy back to the atmosphere. The greenhouse gases in the atmosphere have all come from human activity. Much of the heat that is lost from the Earth's surfaces is re-radiated back into the atmosphere by greenhouse gases. Light energy from the sun warms the surface of the Earth's continents and the ocean.
Answers
Answer:
The correct answer is :
The greenhouse gases in the atmosphere have all come from human activity.
Explanation:
The gases that are able to absorb and re radiate infra red radiation and heat and due to absorbing heat capacity trap and hold the infrared radiation and its heat known as green house gases. These groun house gases include methane, water vapor, CFC, carbon dioxide, ozone and nitrous oxide.
If the green house gases are not present naturally on earth there wouldn't be enough radiation or heat to prevent earth from freezing. The gaseous are form and use through various cycles.
However, a huge amount of carbon dioxide, CFC and methane are added by the human activity into the atmosphere, which is leading to trap heat more than required and cause green house effect.
Thus, the correct answer would be : The greenhouse gases in the atmosphere have all come from human activity.

Winters months are cold and rainy, while Summer months are generally clear and cool. Steady amounts of precipitation throughout the entire year. The precipitation provides rain for lower regions and lots and lots of snow for the mountains.
The mountains are significant for the climate because they keep the moist ocean air from moving away from the coast.
Coniferous forests thrive in this zone.
Both the USA and Canada have arable land. This means that they can use this land to farm, and in turn, their economies are benefited. The Mediterranean west coast provides things for the economy of the USA and Canada that other climate zones can't.
