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?

Answers

Answer 1

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.

those people who lived under mountain what does that mean for them?

Answers

Hill people, also referred to as mountain people, is a general term for people who live in the hills and mountains. This includes all rugged land above 300 metres (980 ft) and all land (including plateaus) above 2,500 metres (8,200 ft) elevation. The climate is generally harsh, with steep temperature drops between day and night. High winds, runoff from melting snow and rain cause high levels of erosion and thin, immature soils. Climate change is likely to place considerable stress on the mountain environment and the people who live there.

People have used or lived in the mountains for thousands of years, first as hunter-gatherers and later as farmers and pastoralists. The isolated communities are often culturally and linguistically diverse. Today about 720 million people, or 12% of the world's population, live in mountain regions, many of them economically and politically marginalized. The mountain residents have adapted to the conditions, but in the developing world they often suffer from food insecurity and poor health. They depend on crops, livestock and forest products, and tend to be poor. In the developed world the mountain people are generally prosperous, and the mountains may be used for tourism and outdoor recreation. Mining is also widespread and dates back to the pre-Christian era.

In parts of the developing world the mountain communities depend on remittances from young men who have gone to work in the lowlands or overseas. Although 70% of mountain people live in rural areas, the rest live in cities, including large cities such as Mexico City, with a population of around 21 million. The cities attract temporary or permanent migrants from the rural areas. The smaller cities are more connected to the mountain culture and economy than the larger ones.

Compound interest at 7%pa on a loan of R5 600 for 4 years .Round your answer to the nearest cents.

Answers

Answer:

Amount of interest = RS 186

Explanation:

Given:

Loan amount = Rs600

Rate = 7% = 0.07

Number of year = 4 year

Find:

Amount of interest

Computation:

Amount of interest = p[(1+r)ⁿ-1]

Amount of interest = 600[(1+0.07)⁴-1]

Amount of interest = 600[(1.07)⁴-1]

Amount of interest = 600[(1.31 - 1]

Amount of interest = 600[(0.31]

Amount of interest = RS 186

What is a nation-state? Why is Korea technically not a nation-state today?

Answers

Answer:

first part: A nation-state is a state that has one centralized government (making it a sovereign state), the majority share the same culture, and their political boundaries and cultural boundaries line up with each other.

(It gets more in-depth political wise but that's the basic idea of it)

second part: Korea is technically not a nation-state today because it is two separate states. North Korea is actually considered more of a cult than a nation-state because of the isolation and sanctions set in place.

not sure if that is the answer you were looking for, if you want me to explain it more in-depth or differently let me know :) hope this helps

From the top of a building 42 feet high, the angle of depression to a car stopped on the ground it is 27°. What is the distance from the car to the base of the building?

Answers

Answer:

[tex]82.43\ \text{feet}[/tex]

Explanation:

Angle of depression = [tex]27^{\circ}[/tex]

b = Height of building = 42 feet

[tex]\theta=90-27=63^{\circ}[/tex]

p = Distance from the car to the base of the building

From the trigonometric identities we get

[tex]\tan\theta=\dfrac{p}{b}\\\Rightarrow p=b\tan\theta\\\Rightarrow p=42\tan63^{\circ}\\\Rightarrow p=82.43\ \text{feet}[/tex]

The distance from the car to the base of the building is [tex]82.43\ \text{feet}[/tex].

Answers

Answer:

The increasing number of social grants that are being awarded by the government are having a negative impact on the nation's unemployment rate. This is so, fundamentally, because although it is obvious that humanitarianly these social grants are positive for the lives of people in need, on the other hand it relaxes them and removes the imminent need to get a job. Therefore, they tend to slow down the employment of these people, making the decrease in the unemployment rate not so evident.
