The station's orbital speed is about 7.69 × 10³ m/s

\texttt{ }

<h3>Further explanation</h3>

<u>Complete Question:</u>

<em>The International Space Station is in a 230-mile-high orbit.</em>

<em>What is the station's orbital speed? The radius of Earth is 6.37×10⁶ m, its mass is 5.98×10²⁴ kg</em>

<u>Given:</u>

height of the station = h = 230 miles = 3.70 × 10⁵ m

mass of the earth = M = 5.98 × 10²⁴ kg

radius of the earth = R = 6.37 × 10⁶ m

<u>Unknown:</u>

Orbital Speed of the station = v = ?

<u>Solution:</u>

<em>We will use this following formula to find the orbital speed:</em>

F = ma

G \frac{ Mm}{(R+h)^2}=m v^2 \div (R+h)

G \frac{ M}{R+h} = v^2

v = \sqrt{ G \frac{M}{R+h}}

v = \sqrt{ 6.67 \times 10^{-11} \frac{5.98 \times 10^{24}}{6.37 \times 10^6 + 3.70 \times 10^5}}

v = 7.69 \times 10^3 \texttt{ m/s}

Answer:

v_o=2503.08\frac{m}{s}

Explanation:

Orbital velocity is the speed that a body that orbits around another body must have, for its orbit to be stable. For orbits with small eccentricity and when one of the masses is almost negligible compared to the other mass, like in this case, the orbital speed is given by:

v_o=\sqrt{\frac{GM}{r}}

Where M is the greater mass around which this negligible body is orbiting, r is the radius of the greater mass and G is the universal gravitational constant. So:

v_o=\sqrt{\frac{6.674*10^{-11}\frac{m^3}{kg\cdot s^2}(5.98*10^{24}kg)}{6.37*10^6m}}\\v_o=2503.08\frac{m}{s}

What is the eulerian description of fluid motion how does it differ from the lagrangian description?
Alex_Xolod [135]

Kinematics : Study of motion

Fluid kinematics : study of how fluid flows and how to describe its motion.

There are two ways to describe fluid motion

one is Eulerian, where the variations are described at all fixed stations as a function of time.

the other is Lagrangian, in which one follows all fluid particles and describes the variations around each fluid particle along its trajectory.

<u>DIFFRENCE  BETWEEN  LAGRANGIAN AND EULERIAN:</u>

1.Both Lagrangian and Eulerian describes time variation.

2. Eulerian describes the rate of change in one point of space

Lagrangian descries rate of change of a property of material system.

A driver has a reaction time of 0.50 s , and the maximum deceleration of her car is 6.0 m/s^2 . She is driving at 20 m/s when su
QveST [7]

Answer:

The car stops after 32.58 m.

Explanation:

t = Time taken for the car to stop

u = Initial velocity = 20 m/s

v = Final velocity = 0

s = Displacement

a = Acceleration = -6 m/s²

Time taken by the car to stop

v=u+at\\\Rightarrow t=\frac{v-u}{a}\\\Rightarrow t=\frac{0-20}{-6}\\\Rightarrow t=3.33\ s

Total Time taken by the car to stop is 0.5+3.33 = 3.83 s

s=ut+\frac{1}{2}at^2\\\Rightarrow s=20\times 3.83+\frac{1}{2}\times -6\times 3.83^2\\\Rightarrow s=32.58\ m

The car stops after 32.58 m.

Distance between car and obstacle is 50-32.58 = 17.42 m
