As the lever rotates around the fulcrum, points farther from this pivot move faster than points closer to the pivot.
Therefore, a force applied to a point farther from the pivot must be less than the force located at a point closer in, because power is the product of force and velocity.
Answer: fulcrum
4 disadvantages of highlands
Answer:
Finding water, growing things, such as crops, all that climbing and no fertile soil
Explanation:
Highlands have four main disadvantages: harsh climate, poor accessibility, limited agricultural potential, and environmental vulnerability.
Explanation:Highlands refer to elevated areas of land, usually located at higher altitudes. While highlands have many advantages, such as their scenic beauty and suitability for agriculture, there are also some disadvantages associated with them. Four disadvantages of highlands are:
Harsh Climate: Highlands often experience cooler temperatures and more extreme weather conditions compared to lowland areas. This can make it challenging for people to live and engage in certain activities in highland regions.Poor Accessibility: Due to steep slopes and rugged terrains, highlands may have limited transportation infrastructure. This can hinder economic development and make it difficult for people to access essential services.Limited Agricultural Potential: The higher altitudes and cooler climates of highlands can restrict the types of crops that can be grown. This can lead to limited agricultural productivity and food insecurity in highland regions.Environmental Vulnerability: Highlands are often more susceptible to natural hazards such as landslides, avalanches, and erosion. These hazards can pose risks to human settlements and infrastructure.In summary, while highlands have their advantages, they also come with some challenges related to climate, accessibility, agricultural potential, and environmental vulnerability.

a shark would not be a good index fossil because
The shark cannot be considered as a good indicator for fossil study. Because the species is known to have survived for a very long period of time.
Explanation:
Fossil studies are done by determining the age of the fossil preserved strata or rock. This is done in order to determine the period of time in which a species found as fossil presence.
Sharks have been known to have survived for a very long duration of time. And, therefore, do not corroborate to a specific period of time. Graptolites and Ammonites are considered as the best index fossils.
Most Pakistanis practice which religion?
A. Hinduism
B.
Islam
C.
Christianity
D. Buddhism
Answer:
b Islam
Explanation:
Answer:
B. Islam
Explanation:
Roughly 97% of Pakistanis are Muslim. Inside Islam, similar to the Christian confidence, there is a division between belief system/religious philosophy. Some stick to the Sunni Islam confidence, which I accept is overwhelmingly the confidence of most Muslims living in Arab nations and the other being, Shia. You catch wind of Sunnis and Shias warring with one another. From what I hear, there is a contrast between these two religions.
which type of map is most likely to show current air temperatures across a region? A. topographic B. weather. C. climate. D. physical
Answer:
B
Explanation:
Usually, weather parameters that are used to populate a weather map, are collected by a wide range of weather apparatus such as barometers, rain gauges, thermometers, and etcetera, from weather stations across cities. The use of the latest technologies such as weather Doppler satellites to detect storms is an addition. Weather maps have lines that join areas with same weather parameters such as isotherms for temperatures and isobars for air pressure.
Weather map is a type of map which is most likely to show current air temperatures across a region.
Answer: B. Weather
Explanation:
Weather maps are used to predict temperatures, precipitation, various types of storm warnings, direction of wind and its speed, chance and type of precipitation, accumulation of snow, frost and lots of other aspects associated with weather. The current information about the weather are communicated through weather maps which is updated frequently. They are the world's most regularly consulted thematic maps.
Isobars and isotherms are lines on weather maps which represent patterns of pressure and temperature. These lines indicates the change in pressure and temperature with respect to the space that helps to determine the larger scale weather patterns of a region in the map.
The Grand Canyon, as seen here, can be compared to a(n) __________ under the Earth's oceans. A) trench B) abyssal plain C) mid-ocean ridge D) continental shelf
I believe the answer would be trench.
Which of the following geological features forms at a subduction zone between an oceanic and a continental plate? A. The lithosphere B. Continental shelf C. Magnetic anomalies D. Mid-ocean ridge
Answer:
Continental shelf
Explanation:
The subdustion zones between the oceanic tectonic plates and continental tectonic plates go in both ways when it comes to the lithosphere. They are both destructive and constructive. With the subduction zone occurring, the crust from the oceanic plate gets into the mantle, gets melted, and thus destroyed. On the other hand, this type of boundary enables the magma from the mantle to penetrate through the crust and reach the surface. As the magma reaches the surface, it starts to create volcanoes, be it in the form of island arcs or continental arcs. The volcanoes then release lot of lava from them on the surface, and this lava cools off and creates new layers of rock. The uplifting volcanoes, as well as the push of the plate that subducts, results in creating a shellow and relatively flat part of the ocean which is alongside the coastline. This shallow and flat part of the ocean is known as continental shelf. The continental shelf is the part of the ocean that has the warmest water, the light penetrates through all of its waters, and it is the most abundant in life. It depth is relatively small.
Answer:
Option (B)
Explanation:
During a convergent collision, the two plates move towards each other, as a result of which the denser plate sinks below the lighter plate. It results in the formation of a subduction zone marked by the trench above it and also leads to the uprising of magma to the surface forming volcanoes.
In the case of a convergent plate boundary between an oceanic and a continental plate, the continental shelf forms along the edge of the continental margin whose slope gradually declines towards the colliding boundary.
Thus, the correct answer is option (B).

Why are most of Earth's deserts located in the subtropical zone?
A. These regions receive less sunlight than the equatorial region.
B. These regions are very warm but less humid than other regions.
C. These regions are very warm but more humid than other regions.
D. These regions receive more sunlight than the equatorial region.
Answer:
B
Explanation:
These regions are very warm but less humid than other regions.
Final answer:
Most of Earth's deserts are located in the subtropical zone due to high-pressure systems causing the lack of precipitation and temperature drops. The rain shadow effect also reduces rainfall in these regions.
Explanation:
Most of Earth's deserts are located in the subtropical zone due to several factors. Firstly, these regions experience high-pressure systems that result in the descending of dry air, causing the lack of precipitation. The dry air doesn't have enough water vapor to prevent the land surface from radiative cooling, leading to drastic temperature drops. Secondly, subtropical deserts are often found on the downwind side of mountain ranges, creating a rain shadow effect that reduces rainfall. These factors contribute to the aridity and dry conditions in subtropical deserts.
3. What determines the maximum rate at which a renewable resource can be harvested?
O A. The nitrogen cycle
O B. Sustainable yield
O C. Desalination
O D. Siltation
Answer:
B. Sustainable yield
Explanation:
The renewable resources are resources that are able to renew on their own. Still, that doesn't mean that these resources can provide endless amounts, but it has to be taken in consideration what is the sustainable yield. We can take the trees as a perfect example. The wood is a renewable resource, but in order for it to be renewable, the trees that have been taken down have to be replaced with young saplings, so that they replace in time the ones that have been removed. If that is not practiced, and much more trees are taken down than what are planted, then the trees will eventually come to an end, and after some time there will be no trees left to be used as a resource.
Sustainable yield determines the maximum rate at which a renewable resource can be harvested. Correct option is b.
The maximum rate at which a renewable resource can be harvested is determined by the concept of "sustainable yield." Sustainable yield refers to the maximum rate at which a renewable resource, such as fish from a fishery or timber from a forest, can be harvested over the long term without depleting the resource's ability to replenish itself.
Sustainable yield takes into account the natural regeneration and reproduction rates of the resource, ensuring that the harvesting rate does not exceed the resource's capacity to replenish itself. It is a crucial concept in natural resource management to maintain ecological balance and prevent overexploitation, which could lead to the depletion of the resource and ecological damage.
Option A, the nitrogen cycle, is a biogeochemical cycle involving the transformation and circulation of nitrogen in the environment but is not directly related to determining the maximum harvest rate of a renewable resource.
Option C, desalination, is a process of removing salt and other minerals from seawater to produce freshwater. It is not related to the maximum harvest rate of renewable resources.
Option D, siltation, refers to the deposition of sediment, such as silt and sand, in bodies of water, affecting water quality and aquatic ecosystems but does not determine the maximum harvest rate of renewable resources.

Syncretism
Semantics
Semiology
None of the above
Answer:
Syncretism
Explanation:
Let's take a look at the meaning of the different possible answers:
Syncretism : That's the merging of different cultural and religious aspects of different cultures into one, ideally blended in some way. Unlike assimilation that is to eradicate the minority without keeping any aspect of it.
Semantics : Is more a philosophical concept of trying to find the meaning of words mostly, and study the languages, human or computer languages.
Semiology : That's the study of the signs, so that's not related to the question either.
I think syncretism is the answer
which of the following is true characteristic of the earth but not the moon?a. volcanoes b. plate tectonics c. molten core d. asteroids impacts
Answer: B.
The Moon's Mantle is too cold to move easily, and has no convection and no active tectonic plate motions, due to the Moon's smaller size and colder temperature than the Earth.
Answer:
The characteristic of plate tectonics is only true about the Earth and not the Moon.
Explanation:
The Moon is way too smaller than the Earth and has a comparatively cooler mantle. The size of the Moon limits the possibility of the existence of tectonic plates. Moreover, a cooler mantle doesn't favour the generation of convection currents that are responsible for the tectonic activities. The moonquakes (like that of earthquakes on Earth) are believed to be caused by the Earth's gravitational influence over the moon and the tidal activities on Earth, not by tectonic activities. Under natural conditions, oceans are _____.
self-cleaning systems
ideal waste-dumping grounds
of no use to humans
most damaged by air pollution
Answer:
Self-cleaning systems
Explanation:
Oceans are natural self cleaning systems that can get rid of any material on their own.
At some parts of the ocean, new crust are being formed. In some other part, new crustal materials are added.
When organisms in the ocean die, they decay to produce some carbon compounds which goes back to the ocean and atmosphere. Their skeletal parts goes to the bottom of the ocean where it compacts with sediments to form new sedimentary rock sequences.
When wastes from land are brought into the ocean, they can be broken down on the long run.
The ocean is self cleaning and it is an effective system as such.

Give a reason for your answer
Yesterday's weather map can be very useful when it comes to predicting the weather for tomorrow, but it also might not be useful at all. The reason why we can not say it for sure would it help or not is because it all depends on the scale of the weather map. If the weather map is only showing us smaller area, then we will not be aware of the surrounding area's weather conditions, and considering how quickly the air masses move, everything can change very quickly. On the other hand, if we have a weather map that presents us much larger area, then we can see the surrounding area and its weather characteristics, so even if the reader of the map is not professional, still it will be able to make a fairly accurate prediction.

The ___ projection map is useful for planning air routes.
Answer:
l vre rad n seo a
Explanation:
The Mercator projection map is useful for planning air routes.
The Mercator projection map is particularly useful for planning air routes because it preserves angles and shapes, which is essential for navigation. This means that lines of constant compass bearing (rhumb lines) are straight lines on the Mercator map, which is very useful for pilots who navigate along such lines. However, the Mercator projection does not preserve area or distance, with distortion increasing with distance from the equator. Despite this, its utility for navigation has made it a standard map projection for nautical and aeronautical charts.
Other projection maps, such as the Robinson, Mollweide, or Goode's homolosine projections, do not preserve angles and shapes and are not as useful for air route planning. The Robinson projection, for example, is used for world maps because it shows the entire world in a way that is aesthetically pleasing and has a compromise between area and shape distortion. The Mollweide projection is an equal-area map, which means it preserves area but distorts shapes, making it less useful for navigation purposes. Goode's homolosine projection is an interrupted map projection that is also equal-area, but it is not used for air route planning due to its interruptions and shape distortions.

There are 75 houses in the troll's street. If in every 4th house there is a pink troll, a blue troll in every 6th house and a yellow troll in every 8th house, then in how many houses are there all of pink, blue and yellow trolls?
Answer:
3
Explanation:
The problem is first to find the Least Common Multiple (LCM) for the numbers 4, 6 and 8 together.
To find the LCM, we have to break down every number into it's prime factors:
4: 2 x 2 = 2²
6: 2 x 3 = 2 x 3
8: 2 x 2 x 2 = 2³
Then for each prime number listed we pick the highest exponent and we multiply them. For 2, the highest comes from 8 (2³), while for 3 there's only one occurrence... so the choice is easy:
LCM (4,6,8) = 2³ * 3 = 8 * 3 = 24
So, every 24 houses, we'll find all three trolls colors.
How many times will that happen within a group of 75 houses?
3 times of course, at houses #24, #48 and #72.
