The International space station is located at the height of \boxed{369\,{\text{km}}}  above the surface of the Earth.

Further Explanation:

The height of the international space station above the surface of the earth is given by the Kepler’s Law of planetary motion. According to this law, the square of time period of the satellite is directly proportional to the cube of the radius of the circular path of the satellite.

Given:

The speed of revolutions made by the International space station is 15.65\,{{{\text{rev}}}\mathord{\left/{\vphantom{{{\text{rev}}}{{\text{day}}}}}\right.\kern-\nulldelimiterspace}{{\text{day}}}} .

Concept:

The angular speed of rotation of the International space station is:

\begin{aligned}\omega&=2\pi\times\frac{{15.65}}{{24\times60\times 60}}\,{{{\text{rev}}}\mathord{\left/{\vphantom{{{\text{rev}}}{{\text{sec}}}}}\right.\kern-\nulldelimiterspace}{{\text{sec}}}}\\&=2\pi\times1.811\times{10^{ - 4}}\,{{{\text{rad}}}\mathord{\left/{\vphantom{{{\text{rad}}}{{\text{sec}}}}}\right.\kern-\nulldelimiterspace}{{\text{sec}}}}\\\end{aligned}

The time period of rotation of the International space station is:

T=\frac{{2\pi }}{\omega }

Substitute \omega  in above expression.

\begin{aligned}T&=\frac{{2\pi}}{{2\pi\times1.811\times{{10}^{ - 4}}\,}}\\&=5520.7\,{\text{s}}\\&\approx{\text{5521}}\,{\text{s}}\\\end{aligned}

The expression for the Kepler’s law is:

\begin{aligned}{T^2}&=\left({\frac{{4{\pi ^2}}}{{GM}}}\right){R^3}\\R&={\left({\frac{{GM{T^2}}}{{4{\pi^2}}}}\right)^{\frac{1}{3}}}\\\end{aligned}

Here, G  is the gravitational constant, M  is the mass of the Earth.

Substitute the values in above expression.

\begin{aligned}R&={\left({\frac{{\left( {6.67\times{{10}^{ - 11}}}\right)\times\left({5.98\times{{10}^{24}}}\right)\times{{\left( {5521}\right)}^2}}}{{4\times{{\left({3.14}\right)}^2}}}}\right)^{\frac{1}{3}}}\\&={\left({\frac{{1.21\times{{10}^{22}}}}{{39.48}}}\right)^{\frac{1}{3}}}\\&=6.74\times{10^6}\,{\text{m}}\\\end{aligned}

The radius of the Earth is 6.371\times{10^6}\,{\text{m}} .

The height of space station above the surface of Earth is given below:

\begin{aligned}h&=\left({6.74\times{{10}^6}}\right)-\left({6.371\times{{10}^6}}\right)\\&=3.69\times{10^5}\,{\text{m}}\\&=3{\text{69}}\,{\text{km}}\\\end{aligned}

Thus, the International space station is located at the height of  \boxed{369\,{\text{km}}} above the surface of the Earth.

<span>373.2 km The formula for velocity at any point within an orbit is v = sqrt(mu(2/r - 1/a)) where v = velocity mu = standard gravitational parameter (GM) r = radius satellite currently at a = semi-major axis Since the orbit is assumed to be circular, the equation is simplified to v = sqrt(mu/r) The value of mu for earth is 3.986004419 Ă— 10^14 m^3/s^2 Now we need to figure out how many seconds one orbit of the space station takes. So 86400 / 15.65 = 5520.767 seconds And the distance the space station travels is 2 pi r, and since velocity is distance divided by time, we get the following as the station's velocity 2 pi r / 5520.767 Finally, combining all that gets us the following equality v = 2 pi r / 5520.767 v = sqrt(mu/r) mu = 3.986004419 Ă— 10^14 m^3/s^2 2 pi r / 5520.767 s = sqrt(3.986004419 * 10^14 m^3/s^2 / r) Square both sides 1.29527 * 10^-6 r^2 s^2 = 3.986004419 * 10^14 m^3/s^2 / r Multiply both sides by r 1.29527 * 10^-6 r^3 s^2 = 3.986004419 * 10^14 m^3/s^2 Divide both sides by 1.29527 * 10^-6 s^2 r^3 = 3.0773498781296 * 10^20 m^3 Take the cube root of both sides r = 6751375.945 m Since we actually want how far from the surface of the earth the space station is, we now subtract the radius of the earth from the radius of the orbit. For this problem, I'll be using the equatorial radius. So 6751375.945 m - 6378137.0 m = 373238.945 m Converting to kilometers and rounding to 4 significant figures gives 373.2 km</span>

What is a scale on a map?
Oksi-84 [34.3K]
A map is almost always smaller than the place it describes. If a map of the US were drawn in its actual size, it would be 3,000 miles wide, and very difficult to fold. ... The scale of the map is the ratio of a distance on the map to the same distance on the real thing. ... If the map scale is 1 : 50000, then 1 foot on the map shows things that are actually spread over 50000 feet in the real city or field.

A car is traveling at 120 km/h (75 mph). When applied the braking system can stop the car with a deceleration rate of 9.0 m/s2.
Bumek [7]

Answer:

the number of additional car lengths approximately it takes the sleepy driver to stop compared to the alert driver is 15

Explanation:

Given that;

speed of car V  = 120 km/h = 33.3333 m/s

Reaction time of an alert driver = 0.8 sec

Reaction time of an alert driver = 3 sec

extra time taken by sleepy driver over an alert driver = 3 - 0.8 = 2.2 sec

now, extra distance that car will travel in case of sleepy driver  will be'

S_d = V × 2.2 sec

S_d = 33.3333 m/s × 2.2 sec

S_d = 73.3333 m

hence, number of car of additional car length  n will be;

n = S_n / car length

n = 73.3333 m / 5m

n = 14.666 ≈ 15

Therefore, the number of additional car lengths approximately it takes the sleepy driver to stop compared to the alert driver is 15

Barnard’s Star is a red dwarf. It is located 5.9 light years from Earth. (One light year is the same as 9.46 trillion kilometers
mote1985 [20]
A star is located 5.9 light years from Earth.
We know that : 1 light year = 9.46  trillion kilometers.
We will calculate the distance in trillion kilometers multiplying the number of light years by 9.46:
5.9 * 9.46 = 55.814
Answer: The distance is 55.814 trillion km.
