A skateboarder starts from rest and accelerates a distance of 485 m reaching a final velocity of 20.0 m/s. How long does it take?
Hello, first we have to look at this part; "The skater starts from rest", which means that the initial speed is zero meters per second.
Once we know that the initial velocity is zero, to calculate the time, we apply the following equation:
s = [(Vo + V) / 2] × t
Like Vi value, is zero meters per second, let's do a simplification in the equation:
s = (V / 2) × t
Data:
s = Distance = 485 m
V = Final velocity = 20 m/s
t = Time = ?
Let's replace the equation according our data:
485 m = (20 m/s / 2) × t
Divide the velocity:485 m = 10 m/s × t
Product's divided:485 m / 10 m/s = t
Resolve last operation:t = 48.5 s
Result:
Takes 48.5 seconds to reach that speed.
how does the pandemic affect food demand and whose food security and livelihoods are most at risk due to the pandemic ?
Answer:
1. The pandemic has negatively affected food demand. A United Nation forecast shows that by the end of 2020, about 132 million people would experience chronic hunger in the world. This is an addition to the 690 million people already hungry today.
2. Those whose livelihoods and food security are at risk are;
a. Vulnerable groups such as migrants, fishers, small-scale farmers, children who are dependent on school meals, sick individuals with special food needs.
b. Developing countries and underdeveloped countries. Small island developing countries are also at risk because they depend on the importation of food.
Explanation:
The Food and Agriculture Organization of the United Nations reports an increase in food demand across the world with the onset and persistence of the pandemic. As at 2019, 690 million people the world over were experiencing chronic hunger. The onset of the pandemic resulted in the addition of 132 million people to this number.
Vulnerable groups such as;
a. Small-scale farmers will experience a hike in the cost of food production and sales.
b. Fishers might not have access to the water bodies for catching fishes.
c. Migrants who do not knw their way around may experience difficulties in obtaining food.
d. Developing and under-developing countries already struggling with their economies might experience difficulties in providing citizens with food through importation.
e. The sick with special food requirements will also be affected.

The two dates of the year when the sun's Direct rays are shining on the equator are March 20 and September 22.
What is the Equator?The Equator is referred to as an imaginary line that segregates the northern hemisphere from the southern hemisphere. The temperature in this region where the latitude is Zero degrees is generally observed as warm.
In contrast to the weather, which varies every hour, climate refers to a weather pattern that lasts for an extended length of time. The change in season is a result of climate change. At the equator, the temperature is usually warm.
The summer solstice occur twice a year on Earth: around March 21 and September 22. apart from the fact that these fall on various dates in the Northern and Southern Hemisphere occurs

Plate boundaries along the islands of Southeast Asia include subduction zones, where denser oceanic plates subduct under less dense continental plates. Analyze the relationship between plate boundaries and physical landforms in Southeast Asia at the regional and national scales. You can infer all of the following except:____.
A. The islands of Indonesia are arcs of islands parallel to the subduction boundary between the Eurasian and Australian plates.
B. The Philippines, which run north-south, are parallel to the subduction boundary between the Philippine and Eurasian plates.
C. Where subduction zones occur, a trench, or areas of extremely low elevation, commonly forms along the plate boundary.
D. The islands of the Philippines run parallel to the subduction boundary between the Australian and Eurasian plates.
Answer:
D. The island of the Philippines run parallel to the subduction boundary between Australian and Eurasian plates.
Explanation:
The island of Philippines is surrounded by subduction boundary zones. The plates of the region moves towards the north west at an average of 6 to 8 cm every year. The subduction boundary is between Philippines and Eurasian plates not between Australian plates.

Once more a mysterious metallic sphere has come to ground in Kansas, and the citizens of Hoxie have called in your consulting firm for help in identifying the material in the meteorite, which appears to have magnetic properties. You rush to Hoxie to investigate, but unfortunately your Hall probe device fails, leaving you with only a strong bar magnet and a sensitive compass. You also have a hammer to knock pieces of meteorite off for study, scissors and some thread. Using these tools, you manage to identify samples from three parts of the meteorite as being diamagnetic, paramagnetic, and ferromagnetic. For your later report, you jot down the measurements and observations you made to establish the identifications. Briefly summarize these for the: A. Diamagnet. B. Paramagnet. C. Ferromagnet

Hope this poem will help you have a nice day :DThe first quartile of a data set is 18, the median is 25, the third quartile is 28, and an outlier is 45. Which of these data values would be represented by a point in a modified box plot? O A. 45 O B. 25 O c. 28 D. 18
Answer: Its A
Step by Step Explanation
Because the outlier is 45
In a modified box plot, outliers are represented by individual points, and the box itself represents the quartiles and median of the data set. The correct option is A.
Five numbers are used to create a box plot: the minimum value, first quartile, median, third quartile, and maximum value. These numbers are used to gauge how closely other data values match them. Use a horizontal or vertical number line along with a rectangular box to create a box plot.
Given that the first quartile (Q1) is 18, the median is 25, and the third quartile (Q3) is 28, we can construct the modified box plot as follows:
Therefore, the data value that would be represented by a point in the modified box plot is the outlier 45, which falls outside the range of the box.
Thus, the answer is option A: 45.

Which statement in the passage reflects the condition of a region in summer?
The different hemispheres receive different amounts of sunlight throughout the year. When the Sun’s rays are concentrated over a smaller surface area, the intensity of radiation is higher. The days are also longer, which means that more radiation is absorbed during a 24-hour cycle. When the Sun’s rays are spread over a greater surface area, they must travel through more of the atmosphere before reaching Earth. The intensity of radiation is also much weaker.
Answer:
When the Sun’s rays are concentrated over a smaller surface area, the intensity of radiation is higher. The days are also longer, which means that more radiation is absorbed during a 24-hour cycle.

Answer:
water in the Earth system.
Explanation:
Earth crust refers to the outermost layer or thin shell which makes up the earth such as sedimentary, metamorphic and igneous rocks.
The Earth crust is typically made up of two (2) main types;
1. Oceanic crust: this crust has a thickness ranging from 5 km to 10 km and comprises of denser rocks such as diabase, gabbro and basalt.
2. Continental crust: this crust has a thickness ranging from 30 km to 60 km and comprises of minerals such as quartz, silicate, feldspar, aluminum and less dense rocks such as granite
The term hydrosphere describes one of the Earth's spheres and it includes all of the water in the Earth system. It makes up about 86% of the earth surface.
